The Monty Gum Superman trading cards were released in 1979 by Monty Fabrieken, a confectionary and printing company in Leiden, Holland. The paper envelope packs contain three cards and a piece of bubble gum. A complete set is comprised of 64 cards featuring images from Superman: The Movie starring Christopher Reeve. The Monty Gum series was released in two sizes with identical images and wrapper art.

The wrappers for the smaller cards read "Made & Printed in Holland" with no additional information. The mini cards contain numbering printed inside of the Superman emblem. The image frames vary in color and the back of each card is blank. There is no copyright information or branding that identifies Monty on the cards. The official logo for Superman: The Movie was not used. Multiple images are repeated or printed in reverse.

During World War II, the Netherlands had become hooked on chewing gum brought over by American and Canadian troops. In 1946, Monty Fabrieken was established as a chewing gum importer in Leiden, Holland, by Huub F.J. Mentink and P.A. De Jong. The name is a tribute to Field Marshal Bernard Law Montgomery, whom Mentink greatly admired. The company depicted the black beret worn by Montgomery on early red wrappers.

Monty began producing trading cards in 1951. The company would distribute card sets for films, musicians, sports, and television shows. In 1984, Monty was subpoenaed by Topps concerning rights to Michael Jackson photographs. A Hague court judge rejected the case. In a 2018 interview, former Monty director Cess Mentink said, "We had never heard of image rights in the Netherlands. We did everything ourselves without contracts and stuff." (auto-translated from Dutch) The company ceased production in 1999.
