Introduced in 1912. Discontinued in 1917. The last and least interesting of the Margin Star series. All that remains in this design is the patterned background. Very rare indeed. I only have one blue single.

Pictured below is a single USPCC Steamboat card with the same patterned background in green. The reverse is an advertisement for a bicycle shop (I’ll post that image soon). Steamboat decks also frequently featured extra cards with advertisements for Bicycle playing cards. Thanks to Steve Bowling for identifying the brand of this card.
