"Carved Coconut, Early 19th Century"
Possibly a powder box or a coconut canteen at the beginning of the 19th century. Work traditionally attributed to inmates of American prisons, these pieces are very appreciated because of the long time required for their realization and the thoroughness of their work. Measures: 16 cm. about.
