A new book, Private Eye - A Cartoon History, contains more than 1,000 strips and cartoons that have featured in the satirical magazine over the past five decades. They include this representation of Harold Macmillan by Trog (Wally Fawkes), which uses the Conservative prime minister's famous 1957 declaration that "most of our people have never had it so good" to comment on the 1960s' sexual revolution.
