The first hockey card sets, generally known as C Series sets, were distributed in cigarette packages by the Imperial Tobacco Company during 1910-1913. The first hockey card set, designated as C56, was issued in the 1910-1911 season, and was called the "Hockey Series" featuring colored portraits of the leading hockey players of that year. This thirty-six (36) card series featured hockey players from the Ottawa, Quebec, Renfrew, Wanderers, and Montreal teams. The forty-five (45) card C55 Series was issues in 1911-12, and the very scarce fifty (50) card C57 series was issued in 1912-13.
