Many works by British artists from the Fifties and Sixties, such as Richard Hamilton and David Hockney, seem no less 'pop' and 'American' than works by Andy Warhol or Roy Lichtenstein. Pop artists on both sides of the Atlantic have borrowed from American popular culture, using the same gaudy formulas and techniques taken from advertising. This book traces the development of pop art in the Fifties and Sixties to the dialogue between British and American artists, documenting its complex genesis in London and later in New York and Los Angeles, and concentrating on the development of its 'pure' characteristics such as sharply outlined images and the use of photographic media. The book not only investigates the connections between American and British artists, but also takes a closer look at the exchange between the East and West Coast of the United States.
