Luc Lafnet was a Belgian artist and illustrator. He was drawn to erotic and fetishistic subject matter, in particular to spanking art and literature. In such publications he used pseudonyms such as Viset, Lucas O., Grim, Davine, Rich, Pol and Jim Black. Below are his illustrations from the 1931 novel Dresseuses D’hommes (Male Trainers) by Florence Fulbert.
