Today’s pic is from John Lamb’s underwater fantasy-adventure The Mermaids of Tiburon (1962). Tim is bad guy Milo Sangster, out to rob the mermaids of their stash of “flame pearls.”
The Queen of the Mermaids was portrayed by Playboy Playmate, model, naturist and belly dancer Diane Webber. Mermaids was turned into a lame “adults only” feature a few years later, when new shots of topless mermaids (with no fish tails, just bathing suits and swim fins) were added and the title was changed to Aqua Sex. Not sure why they even bothered.
