I came across this chart of what seems to be a chart of different stereotypes of some nationalities.
Were these stereotypes wide spread? Are they significant?
Well, looks like it's from the mid 18th century, based on how people are dressed. I'd also guess it was of Germanic origin, given that it's written in Gothic script, which was popular there, and the overall friendly way Germans were described. Given its high quality and full color, it would have been a luxury item.
