I've rarely felt so aroused and hungry at the same time.
You can see all the positions of yumminess at a site created by ardent, philosphical, drug-geek hedonists. What lovely people.
However, they give no clue who the artist is.
Apparently, you can buy the eight-bar set at a snooty chocolate web boutique, although they warn you:
Although tastefully done, the illustrations on these bars are quite graphic and adventurous in nature, including nudity, and are not for everybody.
Well, I wouldn't want anything less!
thanks to monsieur brown for the tip.
