The 1921 W551 baseball card set consists of 10 cards, each measuring approximately 1-3/8” x 3-1/4”. The unnumbered cards were printed in strips, with each front revealing a color drawing of a National Pastime hero. The player’s name and team name are printed in the bottom margin. The backs are blank. The W551 set is made up of Frank Baker, Dave Bancroft, Jess Barnes, Ty Cobb, Walter Johnson, Wally Pipp, Babe Ruth, George Sisler, Tris Speaker, and Casey Stengel. Ruth’s example is by far the most desirable item.
