In light of the “What is it?” game, I have here another image. All you know about this public domain image is the time period and the country (given the fact that it's in the “Late Nineteenth Century America” board). What significant thing does this scene depict?
Well, the Wikipedia Black FridayBlack Friday[/wiki] states about a dozen “Black Fridays”, three of which fall in the latter half of the 19th Century (none of them are it). The most common use for “Black Friday” in my mind is the date after Thansgiving when companies are finally supposed to be operating “in the black” for the calendar year. Hint: think 1880s.
