This is an GPC autographed by Davey Lopes, who made his debut in 1972 with the Los Angeles Dodgers.  The GPC is postmarked April 21, 1973.  The card has been pre certified by James Spence Authentication (JSA). From a Wheatland auction of a lot of autographed baseball index cards and GPC's that I was fortunate to win (see precertification letter).  I am selling the duplicates.
