"Griesbaum's Songbird With Drawer"
A magnificent and original singing bird box, made by K. Griesbaum in Germany in the second half of the 20th century. This brass box features a rare filigree technique. It has a sliding drawer (for jewelry or other small precious items). The box is signed on the drawer and on the base. The mechanism is also signed. When activated, a small bird flies out from under the lid, swaying from side to side while whistling a cheerful song. https://youtu.be/EDWTNtiYYgs
