Art Deco is a visual arts style that emerged in the early 20th century, characterized by its bold geometric shapes, vibrant colors, and luxurious materials. It reflects the optimism and modernity of the post-World War I era, influencing architecture, fashion, and decorative arts. This style is often associated with iconic structures like the Chrysler Building in New York City and the Palais de Tokyo in Paris. Art Deco combines traditional craftsmanship with modern technology, making it a symbol of elegance and sophistication during the Roaring Twenties and beyond.
