The Black Stallion's Filly (plus letter from author)

New York: Random House. NF/VG+. 1952. 1st Edition. Hardcover; 1st Printing. 20, 14. 527216 . 1st edition/1st printing. Stated First Printing. Laid in is a form letter (with, I assume, a printed signature rather than Farley signing them individually though I can't tell if printed or written) telling his readers about a riding camp contest to be held for the winner who sends in the postcard helping him rename the farm where the horses he writes about in his books live. He will choose one boy and one girl for the camp plus give a $100 savings bond to the child who chooses the name he actually uses in his future books. The contest rules are on the back side of the piece of paper (8-1/2 x 11 letter-sized sheet). It has been folded and laid in the book presumably for all these years but aside from the folds, is in excellent, clean condition with the paper in great condition. Pretty neat piece of ephemera! Now, the book. Near fine, straight, clean, tight, with no writing in it; it has a couple of tiny, faint spots to outer page edges, a trace of shelfwear to spine ends and a tiny bookseller's label on lower back pastedown. The dustjacket is price intact, clean, bright, crisp; the spine has sunned somewhat and there are a couple of very tiny edge nicks. .
