1920 – 1940
This French lingerie company from around 1930 was owned by Léon Vidal, and seemed to have been started by Yva Richard who sold his company to Diana Slip in 1920 (since he wanted to focus on his photography more).
The company however was much more then just a lingerie company. They made and sold fetish wear, erotic books, erotic and fetish photography and condoms. Also they established the Librarie de la Lune, most likely a pornographic reading room. Besides all this they produced illustrated catalogs and magazines such as Lingerie Libertines and the Parish Magazine.
Photographers who produced for this company were Brassaï, Jean Moral and Roger Schall, when you take a closer look to some of the photos from the Ostra Studio you can discover some very recognisable lingerie as well so it is my guess that Jacques and Charles Biederer produced photos as well.
I have tried to sort the photos and connect them to the proper photograph, however I noticed many lingerie photos have been attributed to Jean Moral and Roger Schall so take into consideration that I was unable to say for sure if a certain photo belonged to a specific photographer.
