Christie's auction house is offering the Malala portrait, which shows the teenager doing her homework. It has a presale estimate of USD 60,000 to USD 80,000.
Malala, 16, said she will donate all the proceeds from the auction later on Wednesday to Nigerian charities focused on education and advocacy for girls and women.
Last week, the Malala Fund launched a special fund in response to the crisis in Nigeria, where more than 200 girls by terrorist group Boko Haram.
"I was shocked and saddened when I heard about the abduction of more than 200 girls by terrorists in Nigeria. I am very concerned about these innocent girls – my sisters – whose only crime was going to school and learning," Malala said.
"I believe it is our duty to stand together in solidarity with their parents, families and relatives. We all have a voice and we must speak up and call on the international community and the government of Nigeria to intervene and bring these girls back to their homes safely. Together we can create a world where no child will be out of school and no student will fear for her or his safety," she added.
