PB_Behind_Flying_Saucers

Neither the art director nor Earle Bergey himself would let such a golden opportunity slip by... The concept: throngs of seductively-clad women (and one token Gregory Peck look-a-like) scurry about the streets in dire panic at the arrival of a horde of flying saucers. The result: a truly unforgetable cover!

Behind The Flying Saucers by Frank Scully (no relation to Dana that I am aware of) - Popular Library Novel No. 326.

Classic cover art by Earle Bergey.
