Antique porcelain mustache cup decorated with fine flowers 19th century

This delicate mustache cup is made of porcelain decorated with flowers. The mustache cup is a cup decorated with a semicircle of porcelain, letting the liquid pass without moistening the whiskers of sir. This cup comes from a parisian porcelain factory, it dates from the 19th century and is numbered 869. The fine polychrome flowers are painted on the white porcelain background. The handle and borders are enhanced with gold borders (partly erased). In good condition, it measures 11 cm X 8.5 cm. I report a wear and tear of the enamelled decorations.
