MAN FROM ATLANTIS (1977) Jigsaw Puzzle Art

Apparently manufactured and released only in England, these jigsaw puzzles based on the Patrick Duffy aquatic adventure series, Man From Atlantis, sported some funky - and fantastical - artwork. If only the show had presented such spectacles as a giant squid octopus attacking the Cetacean, or Mark Harris duking it out underwater with the Creature from the Black Lagoon's oceanic cousins outside their futuristic sea-city....

I know it's a longshot - but does anyone know who the artist was?
