For collectors who preferred their cards larger-than-life, Topps introduced the 1964 “Giants” series—oversized cards showcasing a stellar lineup that includes legends like Mays, Mantle, and Koufax. With the hobby booming in the early ’60s, Topps looked for bold ways to keep the momentum going, and these jumbo cards were a hit. Today, unopened wax packs from this series are increasingly rare. This example has been authenticated and graded PSA 8, making it a standout piece for vintage enthusiasts.
