Earlier this year, the U.S. Postal Service issued a 39-cent stamp honoring Sugar Ray Robinson (who spent most of his post-boxing life in L.A.). The design of the stamp looked a lot like those vintage fight posters you see in boxing gyms; you could almost smell the liniment. Now comes "Baseball Sluggers," featuring Mel Ott, Hank Greenberg, Mickey Mantle, and the Dodgers' own Roy Campanella. What a whiff. Generic design, drab colors. And, with three New York City-based players, a total lack of geographic diversity.
