With its sleek geometric or stylised forms, Art Deco took the world by storm in the 1920s and 1930s. It was a reaction against the natural, flowing designs of Art Nouveau, which was popular in the late 19th Century and early 20th Century. But one country, in particular, wears the Art Deco crown: France. Because unlike much Art Deco elsewhere, including the US, French Art Deco furniture tended to be hand-crafted rather than mass-produced.
