Ron Oser Enterprises offered this framed and matted piece in April 2000, featuring the original “artwork” (more like a photograph) used for Juan Marichal’s 1973 Topps card, an example card, and Marichal’s autograph.

They described the original artwork as being 3 1/4” x 5”, and the total framed and matted piece as being 10” x 12”
