Dupas worked in various exponents of the Nouveau and Deco areas, such as the fashion magazine Vogue and Harper's Bazaar. In 1925 he showed, at the Grand Exposition des Art Décoratifs in Paris. In 1927, with the aide of the famous French printing house Draeger, he conceived one of the masterpieces of printed advertising, a catalogue for the fur company Max.
Dupas' collaboration in the decor of famous steamships during the 1930's, emphasized the Deco mode of the time. Among these works, the Île-de-France and the Liberté were among the first. But in 1935, with the help of glass master Champigneulle, he decorated the great room of the Normandie, in more than 400 square meters of painted and frosted glass. (Excerpted Wikipedia)
