The Tale of Benjamin Bunny is a children's book written and illustrated by Beatrix Potter, first published by Frederick Warne & Co. in September 1904. A sequel to The Tale of Peter Rabbit (1902), it tells of Peter's return to Mr. McGregor's garden with his cousin Benjamin to retrieve the clothes he lost there during his earlier adventure. In Benjamin Bunny, Beatrix developed the rabbit universe she created in Peter Rabbit, and in doing so suggested that the rabbit world was parallel to the human world, but complete and sufficient unto itself. Benjamin Bunny was an instant commercial and popular success, and thousands of copies were in print by the end of 1904. The Times Literary Supplement thought Beatrix's illustrations "pencil perfect", [1] but suggested that she engage a literary assistant for future productions. Beatrix created a nursery wallpaper tapping Benjamin's image, [2] and he returned as an adult rabbit in the Flopsy Bunnies and Mr. Tod. Benjamin Bunny was adapted in 1992 as an episode of the BBC animated television series The World of Peter Rabbit and Friends.
