Before fandom at large knew that the "D" copies were collected by a man named Davis Crippen, a small portion of the books (like this one here) reached the open market under somewhat mysterious circumstances, wowing collectors with their outstanding condition. Provenance aside, this one's near the top of the census for good reason (only the Mile High copy tops it). E. E. Hibbard drew the cover as well as the interior stories of this comic which is "all" Flash... well, except for a two-pager featuring Butch McLobster the Super Mobster. There's also a recap of the origin of our favorite helmeted speedster.
