(CNN) - Fifty-five paintings by a chimpanzee -- whose works have been acquired by the likes of Pablo Picasso, Joan Mir and the Duke of Edinburgh -- will go on sale at a London gallery in December, collectively priced at around 200,000 ($247,000).
Desmond Morris, the famed ethologist and painter who owns the collection, has decided to sell them at the Mayor Gallery in London.
Over a three-year period, the chimp completed 400 paintings in an abstract expressionist style.
James Mayor, director of the Mayor Gallery, told CNN that many of Congo's paintings are "actually very good."
"He was a fascinating painter," Mayor said.
