Phillips, Rog TIME TRAP
Chicago: Century Publications, (1949). First edition, first printing: a paperback original. Century Book No. 116; cover price, $.25. Mass market paperback. Very faint, nearly invisible crinkling to front cover, negligible wear at spine ends, tiny sideways crease to spine; thus a bright, fine, fresh copy in illustrated wraps. The sublime cover art by Malcolm Smith ranks in our top ten all-time alien pin-ups.
Time travel PBO involves occupation of the U.S. by the Varg Thrott, a mysterious three-eyed race of humans from out of Earth's past. Cover shows a buxom blonde VT in a slinky see-through top giving the reader the come-hither look out of all three eyes.
