Toronto. During WW2, photography found many ways to be of service. This article in the January 1941 issue of Popular Mechanics shows photography making photo I.D. passes that helped separate the workers from the ‘spies’ in America during the war years.
A few decades later, a polaroid colour setup with three differently coloured backdrops helped secure Bell’s data centres by controlling access to the computer area in the pre-internet days when physical damage was a prime threat.
Thanks to my friend and fellow PHSC member, George Dunbar, for sharing this filler article from one of the truly popular magazines both pre-war, WW2, and post-war (I was a fan of the magazine in the 1950s).
Note: The post title is a riff on an excellent movie called, “To Catch a Thief” starring Cary Grant and Grace Kelly (before she became royalty).
