Americans did n’t invent outside advert . That distinction would plausibly have to go to the ancient Egyptians who would put up notices offering rewards for runaway slave . But Americans certainly locomote the outdoor advertising art form ahead in our own ostentatious way during the 20th century .
As you could see from the illustration above , ( by the way drawn by fabled sci - fi illustratorFrank R. Paul ) , coal was feed in into the steam machine below and it would count like the sign was burning red - hot . Exterior luminance would also help shed light on the total video display .
As far as I can state , this idea for the flaming sign of the 1920s never was tried in the real world . Perhaps it would have been a little too terrifying to see the tops of buildings on fire , since Americans were still trying to see out how to mete out withskyscraper fires in the 1920s . But it certainly would n’t be the worst advertising idea of the C . It credibly was n’t even the worst advertising ideaof 1923 .
