I did not know that the "Werewolf by Night" title was a revival of a vintage Atlas comics story highlighted by a cover drawn by Joe Maneely. I stumbled across this fact during my recent Maneely research, and frankly I cannot understand why more is not made of this. Likely it's mentioned in some issue of Werewolf by Night or Monsters Unleashed that I've forgotten about.
The similarity of the covers above by Joe Maneely and Neal Adams respectively indicate an awareness.
Here's a link to the vintage story by Jack Abel, as well as an early installment of Jack Russel's saga under the lush artistry of Mike Ploog.
Also included at this link is a vivid Reed Crandall werewolf story.
