Mysteriously trolling the streets of Paris, exquisitely dressed, Alain found this: a celluloid comb signed by a heretofore unknown designer, E. Burlisson. The shape of the comb, with its black edge, is pure Art Deco. However, the floral designs that fill in the edge are Art Nouveau. Looking at Ancestry.com, I did find a Burlisson family in London in 1891. If the maker is English, the comb did not come from Oyonnax. Perhaps it came from another company in France, England, or America.
