Original World War 2 business industry trade magazine vintage ad for GENERAL ELECTRIC COMPANY of Bloomfield, NJ.  Air Conditioning and Commercial Refrigeration Department.  Sabotage from The Air.  One of the best defenses against dust sabotage is air conditioning with efficient air filtering and accurate control of temperature and humidity. Old 1943 WW2 era propaganda magazine advertisement.  There are remnants of a very old piece of tape on the right edge of the ad, and 5 numbers are written on the bottom of the page.  Would still display nicely matted and framed.
