I’ve seen that poster (or, a copy of one) at the Walter Reed Medical Hospital Museum, the weirdest museum in the US. For instance, they also have a wax head of what someone’s face looks like with uncontrolled syphilis, the bullet that killed Lincoln and the bone fragments from his skull, various posters like this, conjoined twins that died at birth, and all kinds of freaky stuff. And it smells like formaldehyde.
Oooh, I’ll have to go visit there, I love weird shit like that.
I think they have the leg of some Civil War general (Sickels?) that was blown off. I’ve always wanted to go there, but never been in the area.
I have pics of the place, including that poster above. I’ll post them if I think about it tonight.
