South African illustrator and artist Ian Jepson has a series of great classic movie monster posters. Reimagining Godzilla, Alien, and The Mummy, his designs are retro in style and rich in color, feeling both old and fresh, if that’s possible. Beautifully screen printed, his posters are available for sale here, they’d look amazing on a wall in a series. Impressive illustration skills on display, via Behance:
