The book's endpapers had been overlooked. Potter wrote to the firm: "I conclude there is no time to get an end-paper design done—unless Mr. Stokoe has already designed one—I do not mind one way or another; I had begun to scribble something but it looks a bit stiff." Mr. Stokoe apparently did not design one because the endpapers were either plain white or mottled lavender. Several years later, they were replaced with a design featuring a pie and a patty-pan and the cover illustration changed to Ribby sitting by the fire. In the 1930s, the book's size was reduced to bring it into line with the rest of the Peter Rabbit books. The title was changed at that time to "The Tale of the Pie and the Patty-Pan".
