Dating "Cracker Jack" pins
If this poster identifies the source of the pins, then they're from at least 1933. The "Agricultural Building" on the pin at upper center is from the 1933 Century of Progress expo in Chicago.
Edited to add that the poster shows "World's Fair" in the list of subjects. I'd say that pins the date to exactly 1933.
