The 1939 Play Ball baseball card set, the first issued by Gum, Inc., was a landmark set in that it used high quality actual player photographs and a slightly larger card size than its contemporaries. The keys in this set are Joe DiMaggio and, of course, the Ted Williams rookie. This 1939 Play Ball #92 Ted Williams rookie baseball card, front slightly OC to the right, has been encapsulated and graded "EX-MT 6" by PSA.
