These are some very humorous instances of unintentional racism. The people and the signs are innocent enough, and apparently didn’t realize the error of their ways.
Many of the photos were all taken in the days before Pearl Harbor, during the great depression. It was a more innocent time when nearly half of all Americans still lived in small towns or on farms. Mothers still made all of their children’s clothes and color film wasn’t invented until the late 1930s. A very interesting glance at the history.
