I stumbled upon theTumblr blog Keep Calm and Musicals, which combines the ubiquitous "Keep Calm" message with musical quotes/lyrics. There are a bunch of musicals to choose from and some are fun to read. I don't see a poster for one of my favorite musicals of all times - Jelly's Last Jam. Hmmm, I'll have to think about something clever and submit it. In the meantime, here is a sample of posters as reblogged directly from Keep Calm and Musicals and this link to their online shop.
