Ranson illustrated the book La Dactylo Perverse, published in 1927 and written by René Virard.
There is nothing known about the illustrator, no other books with this name as illustrator were found. I am wondering if this could perhaps be the same illustrator as Rene Gontran Ranson (1891-1977) who illustrated books like Menu of Oculiens Oculiennes and Tonus Physicians, 1930 and Gipsys ‘s second dinner April 21, 1937.
René Gontran Ranson also illustrated for the magazine Fantasio, other artists who illustrated for this magazine and did fetish art are for instance René Giffey and Etienne leRallic
I am not sure if this is the same artist as René Ranson, for who I discovered that he illustrated a FemDom Histoire d’O artwork. (see this site)
