All About Prehistoric Cave Men

**The Authors** For All About Prehistoric Cave Men, Sam and Beryl Epstein traveled to England, France, and Spain, where they studied prehistoric art and visited many caves. In the course of their research, they estimate that they drove several thousand miles and walked at least a hundred—about a third of them underground. The Epsteins are the authors of [All About the Desert](/works/OL1590560W/) and more than fifty other books. They live in Southold, Long Island, N.Y.
