Musical automaton by Roullet & Decamps. 38cm high, c1890, Paris.
The pig plays a trombone and lifts his ears and hat. Restored in 2022 with exact replica clothes with mouse embroidery as indicated by the drawing in the 19th century makers catalogue. The papier mache body is finely formed and sculptural so the clothes are easily removable.
