Per http://seriesbookcentral.bobfinnan.com/gms.htm and ABE booksellers, Whitman published this Roy Rockwood reprint series in "the late 30's or early 40's".
- No credit on book or jacket for cover art, but there is a clearly visible signature "J Chambers" which matches examples of Jim Chambers signature at http://www.pulpartists.com/Chambers.html.
