This is Horror Stories for September 1935, cover art by John Newton Howett (same artist, spelling of his name changed between issues). The ISFDB entry for this issue is here. I found this version of the cover in a tweet by Pulp Librarian.
Pulp Parade #56: Sword and stocks
An updated redo of this cover should omit large parts of the stock so we can see what she’s not wearing. 😉
