Artist Carlo was responsible for many bdsm artworks in the 30’s. His art show a very vivid fantasy, like these bondage artworks he did for the book Le Cuir Triomphant, which was published in 1934. The bondage utilities were either used as extra method of torture (combined with spanking or other torture) or solely effective as torture. Pay attention to the details, they show the fantasy of the artist but also shows knowledge of physical condition and how much a body can be bent while being restraint.
