Gocubsgo32 (Gary) recently sold these snaps to me. Thanks again Gary. They were taken at a June 20, 1971 Pirates Expos double header at Three Rivers. They are images of the Parking lot, scoreboard, Bob Robertson during the National Anthem , Steve Blass, Clemente and Stargell at the plate, Pirate dugout, Al Oliver, Clemente running off the field, and a 1970 snap of Clemente and Mazeroski. The last two color photos were taken at the 1971 series. They are of an Oriole groupie
and Three Rivers stadium. I picked up on eBay with surprisingly little competition.
