A quite magnificent singing bird box by Juvenia of France in silver gilt and guilloche enamel. The sides superbly cast in silver in a key pattern with laurel leaves. Sinilar edging to the top but with beautiful and perfect sky blue guilloche enamel inset. The top of the lid hand painted with a Swiss mountain and lake scene in irridescent enamel, underneath the lid are painted roses on a blue background. Superbly feathered bird with ivory beak all operating and singing perfectly. On sliding the operating lever the 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.
