THE ANGRY RED PLANET (1960)
I have no idea if this amazing artwork was done specifically for the movie or was pulled from an old pulp magazine and recycled but it is a thing of beauty. Both of these pieces were painted by legendary Italian illustrator Sandro Symeon and you can see more of his work at this post on the excellent blog Pulp International. Vist the place- you'll be glad you did.
PHANTOM FROM SPACE (1953)
What an achingly great image for a film that really doesn't deserve it. Someone should craft a film worthy of this art. Wow!
