A silver rimmed button with gold text all over a blue background. Two short gold ribbons lie on the blue background and are placed on top portion of the button.
This pre-button commemorates the 20th Session of the International Molder's Union of North America, which was held in Chicago in 1895. The I.M.U. of N.A. was formed in 1859 and represented workers who molded iron in particular. A series of mergers led the union to change its name to the International Molders and Allied Workers Union and, in 1988, it merged with the Glass, Pottery, Plastics and Allied Workers International Union (GPPA) to create the Glass, Molders, Pottery, Plastics and Allied Workers International Union (GMP).
