Lot 56. R313A Gold Medal “Extended Set” of 6. The Gold Medal set is generally considered to be an extended World Series set of R313 Fine Pens featuring 6 members of the St. Louis Cardinals and the Detroit Tigers, opponents in the 1934 World Series. For reasons that remain a mystery, 6 additional cards were produced of 6 additional players which are remarkably rare with only a few copies known of each. Possibly the first time all six have ever been offered. The six players are Al Simmons (excellent front with some album page remains of the rear), Chuck Klein (hairline 1” crease and with some album page remains of the rear), William Rogell (excellent), George Earnshaw (near excellent),Odell Hale (excellent), and Joe Vosmik (some creasing in two corners on front, and used as a postcard on the rear. Mailed in 1935 from Minneapolis.
