Great book covers from the 1950's and 60's

Been doing some research for a competition I'm entering and came across these gems!

New painting, Europa's Escape- went a bit pre-raphaelite in the end though!

Latest painting based on Greek mythology - The Phoenician princess  Europa was abducted to Crete by Zeus. Europa was collecting flowers in a seaside meadow when she came upon a beautiful white bull, she decked its horns with flowers then climbed on its back. Whereupon the bull - actually the god Zeus in disguise - took off at a trot and dove into the sea. Europa was carried off to the island of Crete, where she became the mother of King Minos.

In my painting she is escaping from Zeus' clutches, taking flight on a beautiful horse.
