This very charming carved wooden stopper shows two figures that appear to be wrestling, or the pair are a man and a women with the woman sitting on the knee of the man. Their hairstyles and facial features suggest they are Chinese.
The wood has a beautiful black-brown patina.
Such stoppers were used to close bamboo containers that held powdered lime that was an integral part of the betel quid.
A related stopper is in the British Museum, and a related stopper with overt Chinese influence is illustrated in Schoffel (1981, p. 150).
The example here comes with a high-quality custom-made metal stand.
