Autographed 1949 Bowman of Phillies outfielder Jackie Mayo, signed in blue ballpoint. Its PSA GOOD 2 grade reflects rounded corners, a fold at upper right, and some edge wear. Authenticated and encapsulated by PSA/DNA. Part of a collection of signed 1949 Bowman that was sold at auction more than a decade ago, which we have been offering over our last two auctions. The population report has just four signed examples! Jackie passed in 2014 at age 89 and must've heard every joke related to mayonnaise that you can imagine by then.
