Boris Karloff Tales of Mystery was a title of the 1970s from Gold Key/Whitman, which featured monster stories. What I remember about it from seeing it on the comic racks of its era was the art in each issue seemed uneven to me, a problem I found with most of the anthology comics of the time.
These two stories I found interesting and well drawn. “The Eternity Monster” is from issue #60 (1975), drawn by José Delbo; “The Axeman and the Taxman” is from #68 (1976) and identified (if you can call it that) as being by “West Coast artist?” by the Grand Comics Database.
There are more Boris Karloff monsters at Karswell’s The Horrors Of It All.
