From the Art Daily:
One highlight from the sale is a French carved ivory figural chess set from the late 19th, early 20th century (estimate: £10,000-15,000). Originally forming part of The Allen Hofrichter Collection this detailed historical polychrome example depicts the iconic figure of Napoleon Bonaparte versus the Duke of Wellington.
On the other hand, if that's just a bit out of your budget, then why not settle for the iPad?
