A portrait of a Pakistani teenager shot by the Taliban for championing education for girls will be auctioned next month.
The oil painting by Jonathan Yeo shows Malala Yousafzai doing her homework.
It's being donated by the artist to benefit the Malala Fund, which campaigns for girls' education.
Christie's New York is offering the portrait on May 14, and it's expected to bring $US60,000 ($A64,200) to $US80,000.
It was painted months after the then-15-year-old Malala was shot as she travelled to school in 2012.
