This issue includes Robert E. Howard and H.P. Lovecraft (both writing a Cthulhu Mythos tale) and Robert Bloch and Otis Adelbert Kline and E. Hoffmann Price and Manly Wade Wellman and Henry Kuttner and August Derleth. The only one missing is Clark Ashton Smith, but he got a letter in, so he’s included too. And then there’s a cover by J. Allen St. John and interior art by Virgil Finlay. This entire issue can be downloaded here.
The cover story by Robert E Howard is a personal favorite of mine. The full text can be read here.
