Strange Stories doesn't seem to be as heavily collected as some other weird fiction titles but they had an attractive list of contributors, many of whom were regularly published in Weird Tales.
Writers included: Robert Bloch, Arthur J. Burks, Ray Cummings, August Derleth, Carl Jacobi, David Keller, Otis Albert Kline, Henry Kuttner, C.L. Moore, E. Hoffman Price, Seabury Quinn, Manly Wade Wellman, and John Wyndham.
The covers were mostly by Earle Bergey and the magazine's interiors featured artwork by Virgil Finlay, Leo Morey, and Harry Parkhurst, among others.
I had some interesting Earle Bergey news today. One of the REH scholars and collectors that I know, Patrice Louinet, just got through selling a huge run of high grade Fight Stories on ebay. Apparently the great grandson of Earle Bergey won a bunch of them. He told Patrice that he's working on a book on his famous ancester and doing research Patrice gave him a bunch hi-res scans to use and plans on keeping in touch with him. Hopefully he will get a cool story or two about Bergey.
