Because different countries have very different attitudes towards sex, and the display of potentially explicit imagery it is fascinating to compare the AIDS awareness campaigns between different countries. In some countries it is not acceptable to depict a condom, in others explicit nudity is acceptable. Thanks to the wonders of the internet this is an easy task. First up, the French, because they have had some of the most original, and disturbing images. Arachnophobes should leave now.
“We should all be worried about AIDS.”
"Without a condom, you're sleeping with AIDS. Protect yourself."
There are collections of many more posters here and here at the National library of Medicine.
