COBLENTZ, Stanton A. Planet Of The Knob Heads. Atlas Publishing and Distributing Co Ltd, London 1939 (with Cummings, Ray The Atom Prince). Pp 47, (Atom Prince 48-96) Vol 1 No 5 of “Science Fiction” series. Now bound by a previous collector into patterned boards with silver titling to the spine. A few condition issues, with paper flaws with loss to some margins and loss to small part of leaf in the gutter margin p95/96. Very Good overall. Difficult to find the original printing of this extraordinary title. “ Zuwanna was only postponing the worst, I knew, until she found a suitable knob....she would examine the knobs of newly defunct citizens. But she was not easily pleased. One knob was too small, and one was too large, and one had a crease in it, and one had a spot, and one was too bony, and one was too fatty...” etc etc.
