I don't recall seeing many aviation-themed covers by Herbert Morton Stoops, but this is a good one. I really like the blend of colors on it. Not surprisingly for BLUE BOOK during this era, there are three H. Bedford-Jones stories in this issue--one under his own name, one under his name as well as that of his fictional collaborator Captain L.B. Williams, and one as Gordon Keyne. Other notable writers on hand are Warren Hastings Miller, Leland Jamieson, Kenneth Perkins, William Chester (with a Kioga story), and Robert R. Mill (with a Tiny David story). As a blend of the pulp and slick sensibilities, nothing else came close to BLUE BOOK.
