Civilian Drone Strike, which depicts a trio of Predator drones bombing a children's picture of a house, was auctioned at Art The Arms Fair, a five-day exhibition coinciding the Defence and Security Equipment International arms fair in east London this week.
Money from the sale of the piece was split between Campaign Against Arms Trade (CAAT), and human rights group Reprieve.
Andrew Smith, of Campaign Against Arms Trade, said: "This money will be used to ensure we mobilise even more people against the next arms fair, so that we can stop it from happening". This five-day exhibition formed part of a two-week festival of protest against the Defence and Security Equipment International arms fair in East London this week.
A number of other high-profile artists and activists have also contributed work to the Art the Arms Fair exhibition, including Peter Kennard, Guerilla Girls and Darren Cullen. "It's time to shut it down for good".
During last week's Defence and Security Equipment International (DSEI) fair, Mr Smith said it was "shameful that the government is welcoming despots and dictatorships to the United Kingdom to buy weapons".
