1968 Topps #177 "1968 Rookie Stars" featuring Mets pitchers Jerry Koosman (left) and a young Nolan Ryan (right). The card is from Topps' 1968 set, recognizable for its faux-textured/burlap border, purple team circle, dual photo layout and black nameplates. This is the standard base issue (no refractor/parallel visible) and is prized primarily because it includes Nolan Ryan in his rookie era alongside Koosman.
