In 1950, the cover art was updated with work by artist Bill Gillies. The text was completely rewritten by Harriet Stratemeyer Adams in 1961. The cover art was changed again to reflect the new story, this time by artist Rudy Nappi, and internal plain paper illustrations were added. Only the first two printings of this volume were available in a dust jacket. The book's text and artwork remained the same when the publisher switched to picture-cover illustrated binding editions in 1962.
