Johnny Craig was one of the EC Comics illustrators whose career was revived in the Warren magazines. Here is his original auction art from VAULT OF HORROR #16 (December 1950-January 1951). The story, "Werewolf Concerto", was both scripted and drawn by Craig. It is the only story where the Vault Keeper appears on every page. Monsterologists may recognize the twist ending of this tale to be the reversed in one of the stories that appeared in the first issue of CREEPY, which was illustrated by another EC alumnus. Besides the story, Craig's art was used for the cover. Oddly, the cover for VAULT OF HORROR #17 (see above) was by Craig as well, and could have easily been used for the cover of #16.
NOTE: The pages that follow the original art is the color story from the Russ Cochran reprint (VAULT OF HORROR #5, October, 1993).
