Songs of Innocence and Experience is one of the best-loved poetry collections of all time, an innovative and groundbreaking experiment in which Blake intertwined text and image to dazzling effect. The volume, published sometimes as two separate collections, juxtaposes the innocent world of childhood with the corrupt and repressed one of adults, and includes such favourites as 'The Lamb', 'The Chimney Sweeper' and 'The Tyger'.
