There are many websites and databases dedicated to historical photographs, but I recently found one I think is really neat. It's called retronaut . Retronaut is sort of a Pinterest for historical photos, and its archive focuses on unusual and weird moments in history and pop culture. For example, you've probably seen pictures of Winston Churchill; but have you ever seen him with in his bathing suit  at the beach? Or how about Louis Armstrong playing his trumpet  next to the Sphynx? Now that's what I'm talking about! You might think some of these pictures are Photoshopped, but they're really not. Give Retronaut a try if you want to see historical images you just might not find anywhere else.
