Rembrandt lion drawing raises $18m for big cat conservation at US auction

Chalk artwork sold for record price at a New York Sotheby's auction with proceeds going to the Panthera charity

A tiny chalk drawing of a lion by Rembrandt recently sold for the record-setting price of $18m in New York City to benefit the conservation of big cats.

After selling at a Sotheby's auction Wednesday, Young Lion Resting shattered the previous mark for the most expensive drawing by the 17th-century Dutch painter ever auctioned: the $3.7m Portrait of a Man with Arms Akimbo.
