Another brand continued from the Standard Playing Card Company, which was one of the companies that merged to form USPCC in 1894 but still operated independently in Chicago until around 1930. Throughout its existence as an independent company, SPCC never displayed a brand name on its aces, and that trend continued well after the 1930’s, when it appears that “Uncle Sam” tuck boxes continued to be filled with cards not listing a brand name. The backs shown below (which date from either 1945 or 1965) are identical to the Bicycle Leaf Back design. As you can see, the deck also featured the standard generic USPCC ace and joker from that period.
