Available for purchase through Society6 as art prints, there are 50 different designs to choose from. The skulls are etched with designs inspired by the patterns in art throughout history, ranging from Greek to Aztec to video games (look for the space invaders below!).
My birthday is coming up. These may be at the top of the wishlist.
