While some of these are staged and overtly racist, others appear to be a documentation of the times.
I saw a postcard in a Glacier National Park gift shop in the early 1980’s. It was a holdover from the 1950’s they were still printing and selling. The park borders the Blackfoot Indian Reservation. The card depicted a fat white main golfing with a Native American boy in full traditional garb as his caddy. Now that’s racist.
