The two best makers of French pâte-de-verre glass are Argy-Rousseau and Almaric Walter. Argy-Rousseau made more vases and Walter made more figural items. This Walter example has what collectors want - a lizard. Not sure which kind -- I think it's a chameleon. Walter's lizards are very realistic, colorful and beautiful. This lovely tray, with one lizard against yellow flowers and ivy leaves is exceptionally lovely. 6½" diameter. Signed A WALTER NANCY, the maker, and Bergé SC, the designer. Mint condition.
