Rare Whistling Boy Automaton by Griesbaum, c. 1930s

Triberg, marked in pencil "No. 2", probably a prototype by Matthias Griesbaum, carved limewood figure depicting a barefoot boy seated on a tree stump, with articulated head, two-part base containing bellows, whistle and going-barrel movement wound from the underside, height 9 in. (23 cm). Working order. – Unusual features of the figure – such as the impractical position of the winding arbour and the location of the sound aperture at the back of the tree stump – suggest that it was built as a prototype for a model which did not make production. The movement plays the traditional pedlar's song "I Must Leave this Town".
