Official AL (Brown) baseball shows fine use from the game in which Seaver assured himself immortality in the annals of baseball history. Bold 10/10 side panel inscription tells you everything you need to know: "Tom Seaver, #300, 8-4-85". Added in another hand, "White Sox-4 Yankees-1". Both are in black marker. A defining piece of this HOF hurler's greatness. Obtained from the field right after the game.
