One of the all time great collaborations, Milne's funny, poignant tales of Winnie the Pooh and friends and Shepard's fluent elegant ink drawings. The depth of characterisation and setting is breathtaking, with Shepard placing Milne's characters in real locations in the woodlands of Sussex and animating their every movement with the eye of a master. Shephard was also one of Britain's greatest political cartoonists.
