I love Thai movie posters from the 60s and 70s. The hand drawn ones are really groovy. It's a lost art that is still alive at a few theaters in Bangkok, most notably at the Scala theater in Siam Square. You can get old posters at some secret stalls at Chatuchak Market. My collection is growing, but not as fast as I want it to! Here's a couple of my faves I came across recently.
