I found this (and a whole bunch of equally delicious photos) on a wonderful tumblr account. I stumbled onto it when I was looking for production photos of Mary Poppins. I wound up spending a good hour or two scrolling through the infinity that is tumblr, discovering photo after wonderful photo. This was one of them. I was pretty excited because I've had a hard time finding good photos of Gene Kelly. I guess it's just a matter of looking in the right places.
