Joe Kubert did this surprising torture cover, a teaser for the lead story of Nightmare #12 (1954). I say surprising because it is fairly graphic: hanging people, the rack, hot coals. Ouch! Joe drew his share of horror comics during this period, since he could draw almost anything, but this was a period of heavy criticism of horror comics. This was probably bad timing.
I was disappointed that the Grand Comics Database has no idea of the artist of “Death Stalks the Bayou.” It is extremely well done in an illustrative style. And there are even a couple more torture scenes.
