A substantial portion of his photographic collection, represented by nearly 11,000 glass negatives, was donated by Kodak Pathé to the George Eastman House (GEH) International Museum of Photography and Film in 1974 GEH noted that Chusseau-Flaviens also acquired copies of photographs from other photographers, annotating their names on his glass negatives. They speculated that this accounts for the inclusion of photographs in his collection from various far-flung nations, such as Japan and New Zealand. According to the French Ministry of Culture, his release of the other photographer's work under the Chusseau-Flaviens name created the first photographic press agency of the 20th century.
Countries represented by photographs in the GEH collection include: Algeria, Austria, Belgium, Bulgaria, Canada, Ceylon, China, Denmark, Djibouti, Egypt, England, Ethiopia, Finland, France, Germany, Gibraltar, Greece, Hungary, Italy, Japan, Majorca, Morocco, Netherlands, Norway, Palestine, Philippines, Portugal, Romania, Russia, Serbia, Spain, Sudan, Sweden, Switzerland, Tunisia, Turkey, United States and Yugoslavia. Due to the relative lack of photographs representing France, it has been speculated that a large collection of Chusseau-Flaviens' work remains undiscovered.
Journals in which Chusseau-Flaviens images appeared include Ilustracāo Portugueza, L'Illustration, The Illustrated London News, Le Monde and The Graphic. Fonte
