The card backs are blank. The key card in the set belongs to Babe Ruth.

James Robert Shawkey (1890-1980) was an American baseball pitcher who played fifteen seasons in Major League Baseball (MLB). He played for the Philadelphia Athletics and New York Yankees from 1915 to 1927. He batted and threw right-handed and served primarily as a starting pitcher. Some of his career highlights include being the AL ERA leader and three time World Series Champion. The autograph is distinct and well placed along the side of the player and not impeding the image.
