The National Gallery in London houses one of the richest collections of paintings in the world. As Sir Michael Levey says in his preface to Homan Potterton's guide, "No eye will ever exhaust the enjoyment these pictures provide, and a lifetime spent gazing at them is wisely spent." Homan Potterton, an Assistant Keeper at the National Gallery for many years, tells the story of the growth of this great collection and has chosen nearly 350 illustrations of its masterpieces from all periods. A catalogue of the National Gallery's works is included. 345 illus., 75 in color.
