Learn About Medical Ephemera

Seems like this is the only university or government site, with online ephemera exhibition. Or at least, with more images than other university sites. It surprised me. But, thel other university sites that I have visited, all linked to this one site. So this must be the best around. There isn't an abundant of images here, but is certainly enough to learn about this topic.
