Hundreds of centuries-old snuff bottles, including some used by Imperial Chinese emperors, are expected to fetch up to $5m (£3m; 4m euros) when they go under the hammer in Hong Kong on Sunday, 27 May.
Some of the items, which were used to store tobacco powder, date back more than 200 years to the Qing Dynasty.
