See item #307 for the history behind this button as well as item #308 and real photo postcard #30. This button is 1-7/16" with backpaper from "Williamson Stamp Co./Minneapolis." The text on the button relates to Father Cox, a Pittsburgh priest who led a large group of unemployed to Washington in 1932 to take part in the protests which were staged to get Congress to pay the promised bonus to (largely unemployed) World War I veterans immediately rather than in 1945 as the legislation passed in 1924 had stipulated. Button's upper left edge has a 1/16" air dot and just below it a very faint pinpoint tan dot, both of which are barely noticeable, and the button is otherwise in Exc. condition. Extremely limited and a rare cause button.
