ADDENDUM: The printed catalog list this as one of only four packs ever graded. In fact, it is one of one, the only 'Cello Pack' ever graded.
Extremely scarce 1956 Topps Elvis Presley Cello Pack graded PSA 4. Erroneously labeled as wax pack by PSA which can be fixed by them. Population report shows this as one of only four packs ever graded. A very rare Elvis item!
