A solid silver and hand painted enamel singing bird box by Griesbaum . This is one of his most expensive and elaborate of his output. An outstanding version of this beautiful singing bird model in fine condition and perfect working order. The enamel painting on this box is the finest I have seen of any Griesbaum production, it approaches the quality of 18th century work and is in a different world from the late 20th and 21st century boxes which are being offered as the real thing so prevelently at the moment. The enamel painting to the top and the lid is outstanding. The work to the sides is also exceptional with painted scenes within enamel bordered cartouches and superb enamelling including panels of irridescent enamel, all in mint condition. On sliding the operating lever the enamel lid opens and the full bodied bird pops through the grille & begins singing. It has a moving beak, the bird turns, flaps his wings and tail and after his performance pops down through the grille & the lid lowers. Don't be fooled by modern late 20th and 21 st century copies in gilt bronze and poor painting with plastic gears. This is the real thing. Made in circa 1925 in solid silver. 4 inches wide by 2.75 inches deep by 1.75 inches high ( 10 cms by 7 cms by 4.4 cms).
