POTTER BEATRIX: (1866-1943) English Author & Illustrator of children's books featuring animal characters including Peter Rabbit. An exceptionally fine illustrated A.L.S., Beatrix Potter, four pages, 8vo, n.p. (Ulverston), 11th August 1908, to Master William F. Warner ('Dear little William Warner'). Potter thanks her correspondent for their letter, and that of his sister, and informs him 'I have been trying dreadfully hard to think about another story about “Peter”. I thinked and thinked and thinked last year; but I didn't think enough to fill a book!', further explaining 'So I made a story about Jemima Puddleduck instead - and it will be in the shops very soon. I hope you will like it'. Potter further states 'I must try and do another rabbit book; all the little boys and girls like the rabbits best' and also comments on her current activities and life, 'I am staying at a house where there are lots of wild rabbits in the garden - there is a quite black rabbit [at this point Potter adds the first of her illustrations, a pen and ink drawing of a black rabbit running, executed in a silhouette style] who lives at the top of a bank opposite my bedroom window. When I am dressing in the morning I can see him sitting on a stump washing his face with his paws [Potter adds a second illustration, a pen and ink drawing of the black rabbit seated on the stump, again executed in a silhouette style] I have got a rabbit, but it is brown; I call it Joseph. It is very tame & licks my hands, but I think if it got out, it would run away into the wood. It lives in a hutch and has a nice little yard where it can run about and eat grass. I have got a little brown mouse called Dusty [at this point Potter inserts a third illustration, a simple pen and ink drawing of her mouse seated in profile] it is running about the table while I write, it has been sniffing at this letter. I am sure it wants to send its love to you!' At the conclusion of her letter, alongside her signature, Potter has drawn a fourth sketch, a charming pen and ink fully detailed illustration of Dusty sitting up on his hind legs and apparently eating as he holds his front legs to his mouth. Accompanied by the original envelope hand addressed by Potter. A wonderful and charming letter of excellent content, relating to Peter Rabbit and Jemima Puddleduck, enhanced in its rarity and desirability by Potter's four original illustrations. A neat split to the right edge of the central fold, not affecting the text, illustrations or signature, otherwise VG
