There's no reason to write about that, because it's already a matter of folklore, legend, and public record. This is about Joe DiMaggio the symbol. That too is a very public thing, just like the Empire State Building and the Mona Lisa are very public, very familiar things. And just like any icon, it means something different to each pair of eyes. To me, Mr DiMaggio's death marks the formal passing of the black and white era, in baseball and in American history.
Baseball has three eras.
The ancient era started when baseball crawled from the primordial ooze of the Hudson River to the Elysian Fields of Hoboken, NJ to be born in 1839. If not sepia toned, they are all black and white. Many players whose careers began later, in the late 30s or early 40s, were still around when the first of the memorable color images began to emerge. But these were color pictures, nonetheless. Joe DiMaggio left the game after the 1951 season, the last season in which everything was still strictly black and white.
