Clean 1973 Topps cello pack, authenticated by PSA and graded NM-MT 8.  The front of the pack features Kansas City pitcher Ted Abernathy, but the reverse features the final card of Roberto Clemente.  One of just two packs graded by PSA with Clemente on the back (four have been graded with him on the front as well), this is an outstanding artifact, a well-preserved pack featuring the last card of an American hero.
