As originally published, the dustjacket, endpapers and frontispiece were designed by Welch. Another edition was also released, which included Riordan's autograph, a frontispiece, endpapers, and slipcase. The endpapers are two-tone illustrations, loosely matching the cover's color theme. For instance, on the front cover and endpapers of children's books in 1931. In the endpapers of each volume is a table of the coins that have reproductions. Sometimes the endpapers are used for maps or other relevant information. The book's endpapers had been overlooked. In the endpapers is a list of books that are discussed throughout the book. The now-familiar endpapers of the Peter Rabbit series were introduced in the book. Floca's carefully crafted endpapers also drew notice and praise. Mosse's second play "Endpapers" was part of the Bush Theatre's 2011 project "Sixty-Six Books". Lin was particularly proud of the endpapers and their homage to McClosky's "Blueberries for Sal".
