Lithograph button created by Geo. Haumann, owner of Character Display Co. in Chicago, Illinois. His company made mechanical and animated store displays and 2 known mechanical pinback buttons . This small litho button is the same general design as it's larger 2 1/4" mechanical counterpart. There are two similar versions of the mechanical button, with the donkey kicking the elephant and visa versa. These were manufactured by Green Duck Chicago and then hand assembled by Geo. Haumann.
