In 1956 Mouzillat developed a distinctive art deco branding for RoMo and started to commercialise his collection. He developed a card-based viewing system, using
Bakelite viewers. He sold a wide variety of subject cards, usually with 12 left and right eye images, at newsstands throughout Paris, in France and at trade shows. The catalogues from 1956 and 1957 demonstrate the wide range of geographic, historic and cultural subjects that were documented. He also created a range of cards for children focussing on characters, animals, birds and insects. No accurate count has been attempted of the entire collection but it is estimated that the double images total around 40,000 left and right eye images. The collection can be grouped into specific categories including: • The Regions, Towns and Cities of interest in France and other European countries • The Interiors of the
Élysée Palace • Folklore Costumes of France, Spain, Yugoslavia, Russia and Japan •
Speleology, prehistoric sites of France, grottoes and frescoes • Art Collections in France including interiors of the
Musee Rodin,
Musee du Louvre and Musee de Sèvres • Animals, birds, insects, flowers and butterflies from around the world • Historical and fictional characters from children's literature. ==
