Thrilling Mystery ran from 1935 to 1951, though, like many pulp magazines, it would change its name a few times towards the latter part of its run.  Thrilling Mystery started out with supernatural-themed stories.  In the 40s, it shifted away from the supernatural and became another hard-boiled crime magazine.  The covers below are all from Thrilling Mystery‘s early, horror-themed days.

Unfortunately, I haven’t been able to find any information on who was responsible for doing any of these covers.  If any of our readers can help shed some light on who should be credited for these covers, please let us know!
