The 1970 Kellogg's 3-D Baseball cards came one to a box of cereal and could also be found in individual 3 card poly-bagged packs in some locations.  Simply one of the finest card designs of the postwar period and a real popular one with collectors, this PSA Mint 9 Clemente is a stunner. It's super clean on both sides, remains crack-free and retains its little production nubs  Look at how sharp the image is - just fabulous!
