Art Deco is one of the most influential and recognizable design movements in history. From the lobbies of the Chrysler Building to the streamlined bodies of 1930s locomotives, from the geometric jewelry of the 1920s flapper to the bold graphic posters of Cassandre and Cappiello, Art Deco transformed the visual world of the 20th century in ways that remain vivid and immediate today. Yet despite its ubiquity, Art Deco is often misunderstood — confused with Art Nouveau, with Hollywood glamour, with any vintage design that features geometric decoration. This guide provides the definitive answer to the question: what is Art Deco?
Art Deco: Definition and Meaning
Art Deco — short for Arts Décoratifs — takes its name from the Exposition Internationale des Arts Décoratifs et Industriels Modernes, the major design exhibition held in Paris in 1925. The exhibition, intended to showcase the latest in decorative arts and design, drew twenty million visitors and established Paris’s dominance in international design culture. But the style itself had been developing for at least a decade before 1925, and would continue to evolve through the 1930s and into the 1940s.
At its core, Art Deco is a style that celebrates modernity, technology, and cosmopolitan glamour through a visual language of geometric forms, bold colors, and streamlined silhouettes. Where Art Nouveau (its immediate predecessor) looked backward to nature and medieval craftsmanship, Art Deco looked forward: to the machine, to speed, to aviation and ocean liners, to jazz and the skyscraper, to the entire glittering apparatus of 20th-century modernity.
Art Deco Characteristics: The Visual Language
Art Deco is identifiable by a consistent set of visual characteristics that appear across all media — architecture, interior design, jewelry, fashion, and graphic art. For the poster collector specifically, these characteristics are the key to identification.
Geometric forms. Art Deco uses straight lines, chevrons, zigzags, stepped forms (the Art Deco “ziggurat”), and tight geometric arcs. Where Art Nouveau uses the organic curve, Art Deco uses the precise angle and the calculated radius. The overall effect is of a visual world organized by geometry rather than grown by nature.
Bold color contrasts. Art Deco palettes tend toward strong contrasts: black and gold, navy and ivory, deep red and chrome silver, or the vivid turquoise and coral of the Hollywood and Miami Beach variants. The overall effect is punchy and assertive — designed to be read at speed from a distance.
Exotic influences. Art Deco absorbed visual influences from a remarkable range of non-Western sources: Egyptian revival (after the 1922 discovery of Tutankhamun’s tomb), African masks and sculpture (as filtered through Cubism), Aztec and Mayan architectural motifs, and Japanese and Chinese design elements. These influences gave Art Deco a cosmopolitan eclecticism that was entirely consistent with its celebration of modernity and global connection.
Streamlining and speed. By the 1930s, Art Deco had absorbed the aerodynamic aesthetic of the machine age — the streamlined forms of aircraft, locomotives, and automobiles — into its visual vocabulary. The “streamline moderne” variant of Art Deco uses teardrop shapes, horizontal speed lines, and smooth curved surfaces to evoke the sensation of motion and progress.
Art Deco in Poster Art
The poster was perhaps the most perfectly suited medium for Art Deco’s visual language. The commercial advertising poster demanded immediate visual impact, graphic economy, and the capacity to communicate a message in a single glance — all qualities that Art Deco’s geometric clarity and bold color contrasts provided naturally.
The great Art Deco poster artists — Cassandre, Cappiello, Loupot, Colin — achieved in their best work a synthesis of graphic design, fine art ambition, and commercial effectiveness that has never been equaled. Cassandre’s railway posters demonstrate how Art Deco’s geometric language could be applied to the travel advertising genre with results of extraordinary power; Cappiello’s advertising work shows how the same vocabulary could be adapted for commercial product advertising.

Specific works that exemplify Art Deco poster design include the Mossant hat poster by Cappiello (1938), the Kina Lillet poster by Robys (1937), and the Dubonnet poster (1928) — all authenticated originals in the gallery’s collection.
Art Deco in Architecture and Interior Design
Art Deco architecture is characterized by vertical emphasis, geometric ornamentation, and the use of modern materials — chrome, glass, reinforced concrete — in ways that celebrate rather than conceal their industrial origins. Iconic examples include the Chrysler Building (New York, 1930), the Empire State Building (New York, 1931), and the Palais de Chaillot (Paris, 1937). Art Deco interior design brings the same vocabulary of geometric ornament, bold color, and luxury materials — lacquered wood, mirrored glass, exotic veneers, chrome fittings — to the domestic and public interior.
Art Deco vs. Art Nouveau
Art Deco and Art Nouveau are the two great decorative art movements of the early 20th century, and they are frequently confused. The key distinction is philosophical as much as visual: Art Nouveau looked backward to nature, craft, and the medieval; Art Deco looked forward to technology, the machine, and modernity. Visually, Art Nouveau uses organic curves and botanical motifs; Art Deco uses geometric forms and machine-age imagery.

How to Know It’s an Original Art Deco Poster
Art Deco poster originals are reproduced extensively, and the market contains a significant volume of modern facsimiles marketed as “vintage.” Genuine originals from the 1920s and 1930s were produced by chromolithography or, for some works, photolithography. Under magnification, genuine originals show the characteristic grain of their period printing process. Printer’s imprints — a critical authentication signal — appear on the large majority of genuine Art Deco poster originals. At La Belle Époque, Elie Saporta, co-founder and former chair of the IVPDA authentication committee, applies four decades of expertise to every acquisition.

Frequently Asked Questions
What is Art Deco?
Art Deco is a design movement that emerged in France in the early 1920s and dominated decorative arts, architecture, and graphic design through the 1930s and into the 1940s. It is characterized by geometric forms, bold color contrasts, streamlined silhouettes, and exotic influences, and represents a celebration of modernity, technology, and cosmopolitan glamour.
When was Art Deco?
Art Deco is generally dated from roughly 1920 to 1940, with the 1925 Paris Exposition as its canonical debut and the Second World War as the event that effectively ended the movement’s dominance. The style continued in various forms into the late 1940s and experienced a major revival in the 1960s and 1970s.
What are the key characteristics of Art Deco?
Geometric forms (chevrons, zigzags, stepped ziggurats), bold color contrasts, streamlined silhouettes, exotic influences (Egyptian, African, Aztec), the celebration of modern materials (chrome, glass, Bakelite), and a general sense of cosmopolitan glamour and machine-age dynamism.
Is Art Deco the same as Art Nouveau?
No. Art Nouveau (c.1890–1910) uses organic, curving forms inspired by nature and looks backward to craft and the medieval. Art Deco (c.1920–1940) uses geometric forms inspired by machines and modernity and looks forward to technology, speed, and cosmopolitan glamour.
