Mandela prison drawing auctioned for $112,575

A drawing by South Africa’s first black President Nelson Mandela of the door of his prison cell on Robben Island has sold for $112,575 (£86,345) at an auction in New York – higher than its estimated value of between $60,000 and $90,000.

“The Cell Door, Robben Island” was completed by the late Mr Mandela in 2002 – 12 years after his release from prison for fighting the racist system of apartheid.

Sketched in purple, it shows the bars of a prison cell door and a key in the lock.
