I have never seen a similar generic political poster. This was created in the midst of the Great Depression and the 1932 Presidental race, which Democrat Franklin D. Roosevelt won in a massive landslide beating Republican Herbert Hoover. Roosevelt won 42 states taking 472 electoral votes to Hoover's 6 states and 59 electoral votes.
Please not small losses in left edge.
