Original World War 2 business industry trade magazine vintage ad for FARNWORTH TELEVISION AND RADIO COMPANY of Fort Wayne, IN.  In a Fly's Eye are thousands of separate mirror surfaces.  They give the fly an angle of vision far greater than man's.  Not unlike the Farnsworth Dissector Tube or eye of the television camera.  E. A. Nicholas, President of Farnsworth Television and Radio. Old 1943 WW2 era propaganda magazine advertisement.
