London Underground posters, originally intended to advertise destinations served by the Underground, are now regarded as works of art in their own right. Posters from the great age of graphic design, the 1920s and 1930s, now sell in great numbers in reproduction. The original artworks, even the original posters, are extremely valuable. This collection, from the archives of the London Transport Museum, features all the London Zoo posters from 1910 to the present day, and contains detailed captions, notes on the artists, and a brief history of the Zoo itself. It is a companion volume to "By Underground to Kew".
