As referenced by Huffington Post, there is a wonderful collection of 27 never-before-seen photos of the 1955 World Series from Life magazine. My favorites are two of Jackie Robinson, stealing home in the eighth inning of game one. What 'nads.
From the caption of one of these two photos: "...Brooklyn would not win this game, but Robinson's steal made it plain that they weren't going to let the yankees simply walk away with the title. It was going to be a battle to the very end. (For what it's worth, an awful lot of people who have reviewed the play in the years since believe that the ump, Bill Summers, blew the call. But probably even more are happy to believe that Robbie pulled it off.)"
There is also a great sequence of photos of Jackie, boldly "dancing off of third," daring a throw. Again, from the caption: "This picture is from the same series of Morse photos that produced perhaps the single most famous image of Jackie Robinson ever made -- a portrait of the Dodgers' second baseman in full-on "rile 'em up" mode that has become, 55 years later, an emblem of competitive fire. This, the picture says, is the guy you want on your team."
