I found this in a box with a bunch of family photos and documents that date back to the 1880s. I don't know who the woman or any of the men are, I know that I had family who lived in Germany at the time. But I can't find any other pictures of this woman. I know the Opekta ad in the background means this is probably pre-1940, and I think the Nazi pricks are SA, but what are their ranks or if I'm wrong, their branch/role?
