Robes et Manteaux published in 1974

This is a rather strange magazine, and I can find no information on it's origin. It contains only pictures (no avertisement) of  three swiss brands or designers (E. Braunschweig, Cortesca and R. Cafader) from their Prêt-a-porter Paris Collection. It was a trimestral publication, this one being spring/summer 1974. Here are some pictures and more to come!
