Here's a fun game you can play! It's called Spot the Swipe. All you have to do is spot a piece of art that has been copied from another source (a photograph, another painting). This will usually be just a face, or a pose. For our purposes, these should be swipes from classic horror/sci-fi/fantasy flims. Could be from an old pulp, paperback, or just about anywhere.
Here's one sent in by John from Monster Magazine World. It's from an old (1946) paperback called Spawn of the Vampire and it's pretty obvious that the head was swiped from this photo from The Mummy (1932).
Email your swipes to me and keep your eyes open!
