Tight and almost square. Spatter on top page block on half next to spine. Age-tanning is mild to moderate and uniform, due to the paper choice of publisher. If you are seeking this (only) printing with this cover - you will probably not find any better.

All later books appear as by "Leo P. Kelley" - so I assume this book perpetuates a typo by the publisher. Cover art is uncredited - but obviously by Jack Gaughan. This cover art was later used for the Leisure Books edition of The Alien by Raymond F. Jones.
