Note: 200 illustrations That may be an estimate, from "Stories for Older Young Folks", NY Herald Tribune 1947-11-16 pE7 (uncredited, unusually positive): For anyone who knows the story, "these two hundred drawings make a new book of it." "... At last, by self-sacrifice on behalf of a feathered friend, [Nils] becomes a boy again. All this follows from one drawing to another; the design and production of the book is a joy to eye and mind."
