Jacobsen

Jacques Lemonnier (born July 17, 1958) is a comic illustrator of French origin. Using a multitude of pseudonyms (Jakez Bihan, JAK, Jack Whip), readers of this article will most associate with Mr. Lemonnier's use of the pen-name Jacobsen.

Granted, most of Jacobsen's work in the erotic is heavy in BDSM and mostly unrelated to futanarism, but the transsexual content in the Mathilde et Gilda series is why further reading is suggested. If you have any inclination to read Franco-Belgian comics or BDs (bandes dessinées), be sure to look at Céline and Miss Butterfly.
