Peter Fendi was an Austrian painter, engraver and lithographer who got his kicks making watercolors and lithographs of fancifully explicit sex scenes. Fendi was a child prodigy and was accepted into the St. Anne's Academy of Fine Art in Austria when he was 13, then went on to create these explicit and wonderfully weird artworks. Art historians are unsure whether Fendi himself actually did these paintings, but in any case they're worth looking through, if not for the artistic value than for the impressive feats these characters perform during intercourse.
