Of the more than sixty baseball stamps issued by the United States since 1939, the vast majority commemorate individual players. Many of these postal portraits feature specially commissioned artwork designed to mimic the look and feel of classic baseball cards and recall players whose achievements on and off the field made them household names. Here, for the first time, original stamp art and production material from the USPS Postmaster General’s Collection is paired with actual game-used artifacts as a powerful visual reminder that these players— whom most of us know only from photographs and old footage—were once flesh and blood.
