MAN FROM ATLANTIS (1977) Promo Art

Here's an unusual bit of promotional art for the Man from Atlantis television series. I'm not sure where it was used (although I'm guessing it was a magazine cover or interior illustration), nor can I quite make out the signature. Still, it's pretty cool!

If anyone has more information on this piece, please post it in the comments - I always like to know where this stuff comes from!
