An exhibition celebrating 50 years of the Mouth & Foot Painting Artists (MFPA) is on at the Royal College of Art. This picture of Neuschwanstein Castle is by Steven Chambers.
The MFPA was founded by Eric Stegmann, from Germany, who painted using his mouth. Norfolk artist Peter Longstaff, who painted Doves, has disabilities caused by thalidomide.
More than 600 artists are registered with the MFPA. Once they reach a professional standard they get a salary for life. Somerset artist Daphne Allan is also affected by thalidomide.
Trevor Wells discovered a talent for painting after breaking his neck when he was 20. His pictures - like this one of Lake Windermere - have an almost photographic quality.
Tom Yendell, who runs the MFPA gallery in Hampshire, paints using his feet, having been born without arms because of thalidomide.
George Hopkins is ten years older than the MFPA itself - he was born in Kent in 1946. As a result of cerebral palsy he does not have the use of his hands.
Richard Wood was paralysed after a diving accident at the age of 21. He began painting using his mouth while staying at a spinal unit in Wiltshire. He is a student artist of the MFPA.
Ian Parker was born with a medical condition which meant his joints were permanently fixed. He started painting at school and has a degree in fine art.
Perhaps the best-known MFPA member is artist Alison Lapper. She shot to fame when a statue of her naked and pregnant went on display in London's Trafalgar Square.
