For more than 50 years, glassmaker August J.F. Legras worked in Saint-Denis, France. Legras produced acid cut-back cameo and enamel wares from the middle of the 19th through the first part of the 20th centuries. He produced commercial cameo glass vases until  1920 when  Art Nouveau began to make way for Art Deco. Legras marked this last decade  decade with transitional designs  all-out geometrical designs, produced for Paris’s Exposition des Arts. Charles Legras died in 1922 and Théodore sold the business in 1928, neatly missing the Wall Street Crash.
