A strange rescue effected on this cover of Planet Stories (Spring 1946) by Harry Lemon Parkhurst (1876-1962). I have no vey clear idea what “thrallmery” means. The word does not appear in either Wiktionary or the Oxford English Dictionary. Henry Kuttner’s story “What Hath Me” has some rather surreal interior art by an artist identified only as “Hollingsworth.”
This is Spicy Mystery Stories for February 1938, cover by Harry Lemon Parkhurst, as well as a story by the ever-so-plausibly named “Justin Case.” The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers.
Time for a new series: Spicy Mystery Stories, rarely outdone for pulp salaciousness. This is their July 1935 cover, done by Harry Lemon Parkhurst. The ISFDB entry for this issue is here. The version of the cover above is from Pulp Covers. The version accessible through the Galactic Central index is smaller but shows less wear.
My original tumblr post was here. This image is the cover of the Winter 1945 edition of Planet Stories. The ISFDB entry for the issue is here and provides the same cover in slightly less washed-out color.
