Wow this is a coincidence. I watched a documentary about something in the 30's or 40's in the last month and they showed a downtown building with a scrolling news feed a bit like the CNN/SkyNews "ticker tape" and my first thought was "that can't be right, how could they show scrolling text back then?".
Wow, the guys climbing around the signs to clean them and replace the bulbs are doing so without a safety harness!
But since OSHA, (Occupational Safety and Health Act) wasn't in existence before 1970 I guess such practices were common place.
Similar to the iron workers for building skyscrapers.
I think I'll stick with my curent job!
