Great photographs courtesy of Powerful Pictures and Classic Pictures on Twitter

I saw the above picture a few weeks ago, failed to download it, and, having thought about it every day since, spent an hour online yesterday tracking it down to the Powerful Pictures twitter feed. All of the following photographs are from that feed or Classic Pictures (if you're on Twitter, just put those titles into the search box). Here are some more of my recently-tweeted favourites (and, yes, I know I'm being dreadfully sentimental):
