The story goes, that on 4/9/32 while playing in an exhibition game for the St. Louis Browns, Hall of Fame slugger "Goose" Goslin came to bat with his infamous "camouflage" bat. Goslin had this striped bat made, so he could confuse opposing pitchers and fielders. He got away with it in the preseason game against the Cardinals, however when he brought the striped bat out for the 1932 season opener, the umpire forced him to use a bat with a regular finish, and the next day AL President William Harridge permanently outlawed the use of camouflage bats. 

Here we have an oversized transparency of Goslin holding his camouflage bat. Sized at 12x18, this ancient publication piece remains in excellent condition, with light to moderate wear. A caption at bottom reads "Leon Goslin, Star Slugger of the St. Louis Browns, and His Famous Paint". Obviously, the rest of caption would read "ed Bat". Reportedly, the photo from this oversized transparency was printed in the August 1932 issue of Baseball Magazine.  Opening Bid $50.
