In 1946, Ralston Purina sponsored a radio show called Tom Mix Radio Show. These decoder radio premium buttons feature 3 of the 5 characters of the "Straight Shooters Club". Curley Bradley, Wash and Tom Shaw. You will receive all three.
They measure 1" across. The words, Yes, No and Danger Ahead appear on the backs. Normal age wear and one has some discoloration on the back.
Great starter set!
