Known as the father of the modern poster, Jules Cheret (1836 - 1932) was a French painter and lithographer. He worked on everything from theater to advertising. Using only her last name Lily de Lidia graced some of the most popular music-hall stages of the day with her ''gommeuse'' (double-jointed) act. This poster announces Lidia''s appearance at the outdoor Alcazar d''Ete. Cheret depicts the artiste in a half-length view that''s rare for him. Her expression is winsome, the creamy expanse of her decolletage appealing, and the overall design full of movement, from the sweeping ribbons of her hat to the swaying letters of her name.
