...for Ronald Searle, Britain's greatest living cartoonist, who is celebrating his 90th birthday. His career, which began on the Cambridge Daily News in 1935 was interrupted by the Second World War and four years of imprisonment and hard labour in Japanese prisoner-of-war camps. He is perhaps best known for his St Trinian's drawings, the first of which he sketched in Changi jail, but his art , while rooted in the English comic tradition, ranges across many subjects and appears in several leading magazines in Britain, France and the United States.
