Diana Slip, a French lingerie company from the 1930’s owned by Léon Vidal. To say that they were a “lingerie company” is actually a bit loose . To be clearer, it was more like part of a erotica-supply conglomerate that made and sold fetish wear, condoms, erotic books and photography, and established the Librarie de la Lune (which I’m assuming is a pornographic reading room, but I haven’t been able to find concrete information on that.) They also produced a series of illustrated catalogues/magazines (including Lingerie Libertines and The Paris Magazine) with excellent fine art photographers such as Brassai, Jean Moral and Roger Schall.
