Richard Clifton-Dey (May 29, 1930 - April 5, 1997) was a Yorkshire-born British artist. He started painting in the 1960s and was one of the most highly respected of British book cover illustrators during the 1970s and into the 1980s. The Dorian Hawkmoon series by Michael Moorcock featured his art.
Cover artist for Imagine #30.
Note: This appears to be a different person than Richard Clifton, a self-taught artist from Delaware known for his waterfowl artwork which adorn various duck stamps.
