The book Diane Gantée was illustrated by Leon Pierre, I found this cover art I had never seen before. Not even sure if this was done by Leon Pierre but I decided to share it here, the other images for this book are available for members at my other site.
The art from this artist (also known as Y.Vanoff) is a mixture between bdsm and spanking art. There are some really nice artworks to discover at Vintage Fetish Art
For this illustrator it was really, really hard to find images. Victor Spahn was illustrator for femdom flagellant novels, published by Jean Fort. Members have access to all 14 images. via Victor Spahn — Vintage Fetish Art
