Who Were They?

This undated photo shows a young Girl Scout saluting with a backward three-finger salute. She has a tie, belt, hat and a shawl or coat over one arm. You can just see over her left pocket a round Girl Scout symbol, and in the center of her tie her pin. This uniform looks similar to those worn in the 1919-1927 era, although not exactly like others I have seen from that time. I’m venturing a guess at the 30s. The back of the photo says “Sis just before she left for camp.”
