"Know for Sure" STI Poster Fights Venereal Disease
Created in 1944, this is an image designed to reduce the spread of STD's by pre-marital blood testing. In this image, the man is presumably getting ready to carry his new bride across the threshold on their honeymoon. But how can he be sure things won't go horribly wrong unless he's had her tested for diseases? Of course, the image goes just as much for the woman, but the impression given is that a man must have his lady tested for STD's "just for sure."
