This 19th century Viennese enamel and silver gilt snuff box depicting the figure of Napoleon Bonaparte (1769-1821) was made by the celebrated Austrian goldsmith and jeweller Hermann Böhm (1866-1922).
Possibly commissioned by a client who admired the French leader, the 3in (8cm) wide box opens to reveal a purple interior with a crown on a cushion and an eagle, and a capital N to base. The box is estimated at £300-500 in the Bishop & Miller sale in Stowmarket, Suffolk, on February 24.
