A baseball card is a type of trading card relating to baseball, usually printed on cardboard, silk, or plastic. In the 1950s, they came with a stick of gum and a limited number of cards. These cards feature one or more baseball players, teams, stadiums, or celebrities.

The Goudey Gum Company was an American chewing gum company started in 1919. The company was founded by Enos Gordon Goudey (1863–1946) of Barrington Passage, Nova Scotia. Formerly an employee of Beemans, he opened a factory in Boston, Massachusetts in 1919 and later in Allston. It operated there from 1924 until it closed in 1962. Goudey sold the business in 1932 but he retained an interest as a consultant. On his retirement in 1933, William Wrigley Jr. dubbed him the "penny gum king of America". Today the Goudey name is mainly associated with its collectible baseball cards which were introduced in 1933. Goudey was the first American company to issue baseball cards with each stick of gum.
