"The Pie and the Patty-Pan" was published in October 1905 in a large format, priced at one shilling, and dedicated to Joan, the sixth child of Potter's former governess Annie Carter Moore, and to Beatrix, Mrs. Moore's newborn and Potter's god-daughter: "For Joan, to read to Baby". "The Pie" was the first of Potter's books to be published in a format larger (177 mm by 138 mm) than the standard size (139 mm by 104 mm) of the Peter Rabbit books; and the first of her books to integrate pen-and-ink and colour illustrations between its boards.
