The set that started it all. Series 1 introduced GPK × MLB in October 2022 as an online-exclusive Topps release featuring artwork from Keith Shore — a longtime Topps collaborator best known for Project70. Shore's pop-art style gave 15 MLB stars the full GPK grotesque treatment. With an estimated 60,000 packs printed, this set is meaningfully scarcer than secondary market availability suggests, and the parallel rainbow bottoms out at Red Foil /5 and a Gold Lava 1/1. Two player autos exist: Bobby Witt Jr. and Julio Rodríguez, both numbered to /99.
