Life has some of the best photos of the past century available online, many in handy galleries. Take, for instance, this gallery of baseball players in their clubhouses, it's simple, easy, and pretty awesome. And by that I mean the "inspiring awe" definition when one sees Willie Mays back in the day.
My goodness that man is jacked. No wonder he hit 660 homers. Hell, I'm shocked it was only that few.
