In the 50's and 60's it wasn't hard to find the lovely Diane Webber in any number of men's and nudist magazines. She was a sought-after model who wasn't afraid to bare it all in front of the photographer's camera. In this pictorial from BATTLE CRY (February 1964) she keeps her clothes on -- well, most of the time.
Two years earlier, Miss Webber starred in the fantasy/adventure film THE MERMAIDS OF TIBURON. She was in a few other genre films, SINTHIA, THE DEVIL'S DOLL for one, but besides being an unabashed nudist, her greatest achievement was becoming a world-class belly dancer.
