1948 Kellogg’s Pep Stamps-2 of 5 BB players in set- Mike Tresh & Orval Grove-ex.

Not really a stamp–small 1 3/8″ 1 5/8″ card designed to be mounted in a collector’s book supplied by the company… From a World Celebrities Set produced by Kellogg’s cereal in 1948. Only 5 baseball players are in the set. Tresh and Grove are both Chicago White Sox. Hard to find unmounted with clean backs– both are excellent with small 25 written on back in upper left corner.
