War With The Gizmos by Murray Leinster, 1st printing 1958.  Features great 50's cover art.  Book is in nice condition with edge wear, cover creasing and a couple of small tears in front cover.   Spine is tight, pages are supple and book lays flat.  Winning bidder to pay $3.75 bookrate S/H (int' higher--see payment instructions).  Good Luck!
