"Images of an Era: The American Poster, 1945-75" was an exhibition organized by the Smithsonian's National Collection of Fine Arts in 1975. This original lithograph exhibition poster was designed by American artist Ivan Chermayeff and is in great condition for its age and unframed state! This collection celebrated one of the real American art forms as the nation readied itself to ring in the bicentennial - here we are in our 250th year, and bold, unapologetic graphic art is still as American as apple pie!
