John Bolton (born 23 May 1951, in London, England) is a British comic book artist and illustrator most known for his dense, painted style, which often verges on photorealism. He was one of the first British artists to come to work in the American comics industry, a phenomenon which took root in the late 1980s and has since become standard practice.
Bolton's introduction to comics came about quite casually after he graduated from East Ham Technical College (whose former alumni include Gerald Scarfe, Barry Windsor-Smith and Ralph Steadman) with a degree in graphics and design.
His first works in Great Britain were for magazines like Look In (alongside other British talents such as Arthur Ranson, Angus P. Allan and Jim Baikie), The House of Hammer and Warrior (edited by Dez Skinn).
In 1981 Marvel Comics' editor Ralph Macchio noticed his work and called him to work for an adaptation of Kull of Valusia for Epic Comics.
