Original World War 2 business industry trade magazine vintage ad for GENERAL ELECTRIC COMPANY of Bloomfield, NJ.  Death Leaves a Fingerprint.  Probably it was hot and humid in the assembly room, that day when warm, perspiring fingers accidentally touched a tiny shaft.  But the fingerprint remained, acid, corrosive.  Just because of a fingerprint, a many may die.  Another war job for air conditioning.   Old 1943 WW2 era propaganda magazine advertisement.
