Edited by Anthony Boucher. Compiled by members of the Mystery Writers of America. Topics include Roy d'Autremont, Ed Gein, and Charles Starkweather, and the full listing of articles and authors is on the back (see pics). Elegant Mad Men-esque cover design on this rarity as well.
This 1962 first is in nice shape; a previous owner/seller added a plastic binding, so while the jacket shows normal aging (particularly to the corners), it's also pretty safe from further wear. Some writing from other shelvers on the flyleaf, but otherwise the pages are clean and tight.
