Wheaties is an American breakfast cereal made by General Mills. Many sports stars from basketball, football, the Olympics, and baseball have appeared on the cereal boxes. The panels could be cut out and be collected as cards, typically 6" x 8-1/4" in size. In the baseball card standard catalog the sets are given the BB designation for "Breakfast Box". From 1936 to 1939 multiple sets were released in the same year. In 1940 and 1941 multiple cards were included on each box back, the designation changed from BB to M. In 1951 and 1952 the cards came from the single serving size boxes so they were more typical baseball card size. Finally in 1964, the set was a stamp set with an album.
