This is the article that followed the Dave Cockrum Creature From the Black Lagoon illustration you saw in yesterday's MONSTER MAGAZINE WORLD post. It's from Marvel Comics' MONSTER MADNESS #3, published in 1972 and must be one of the "Fiendish New Feautures" seen emblazoned on the front cover.
Note should be made of the two authors as well. Allan Asherman was a writer of several DC Comics titles and went on to become the publisher's historian. Gary Gerani was the writer of FANTASTIC TELEVISION, and more recently the DEATH SHIP comic mini-series that explained what happened aboard the doomed ship Demeter on its voyage from Europe to England, carrying in its cargo hold the most famous vampire in history.
