1970 Topps #189 Thurman Munson Signed Autograph RC POP 1 of 4 PSA/DNA Slabbed
This is one of those special holy grail cards. Munson died tragically young, and while he was alive, he did not like signing autographs. This card is 1 of 4 in the PSA Pop report, and is likely the only one for sale on the open market.
