Now this is fun! Note that one of the putti at top has an erection, and the other one is a girl! It’s quite rare to see blatantly female putti like that. And all the stuff going on at the bottom . . . très amusant. Chauvet, a student of Eugène Ciceri, produced this when he was twenty years old, providing the date is correct.
Jules-Adolphe Chauvet – The Centre of the World (1848)
This drawing reminds of “L’origine du monde” by Gustave Courbet.
Note that the French put a hyphen between his two forenames: Jules-Adolphe Chauvet. See for instance http://top-terriens.fr/star-jules-adolphe-chauvet.html where exactly the same image as yours is shown.
There is a French Wikipedia page on him, it says that he made drawings for Gay et Doucé, a Belgian publishing house specializing in erotic works. Some of them can be found in http://le-bibliomane.blogspot.fr/2011/03/les-editions-gay-et-douce-illustrees.html
On the other hand, Wikimedia commons has only one erotic image by him (18th century lesbians).
