At first glance, this artwork looks like your typical piece of baseball memorabilia, signed by more than 40 celebrities, including Mickey Mantle, Sandy Koufax, Willie Mays and even president Richard Nixon. But this is no ordinary showpiece. It’s not LeRoy Neiman artwork or a piece created by famed sports artist Ron Lewis. No, the man who took credit for creating this rendering also took credit for raping and murdering 33 young men and boys: John Wayne Gacy.
