In February of 1972, the English sculptor Henry Moore, preparing for a large exhibition in Florence, took breaks by retreating from his studio to a smaller edifice in a nearby sheep pasture. He became entranced by the animals and spent weeks sketching them: alone, together, and while suckling their young. The resulting picture book — which Moore presented to his daughter, Mary — perfectly conveys the fuzzy creatures’ simple innocence and is sure to beguile the eyes of children in their animal-obsessed stage.
