Vintage Poster collection for sale.  Posters as an art form were invented by Jules Chéret in Paris in the 1860’s. Their proliferation and refinement were the result of advances in printing technology, a relaxation of laws regulating the press, and a booming demand for the advertisement of ‘modern’ products and of the Parisian lifestyle in the Belle Epoque (1871 – 1914). In journals, books, theater programs, and posters, the graphic arts soon transcended their commercial function and became art objects sought out by art collectors worldwide.
