Matt---in 1993 Topps licensed R & N China Company to produce some of the 1993 set in porcelein. I am not sure if the whole set was reproduced but some of it was. I don't think it sold well but it was apparently decided to produce such porcelein reproductions for some of the major stars in their older cards. There was a complete run of Mantle Topps cards and for some other stars too, like Mays. For Mantle I think since Topps owned the Bowman rights too, his Bowman cards were also reproduced. They are actually kind of neat and I bought a couple of examples that I keep with my sets. You can usually find some under an ebay search for "R & N China Topps" I know Larry Fritsch sells a complete run of the Mantles
