The Royal Story was one of the few Canadian reprints. The original edition was published in hardcover by McGraw-Hill in December 1952. The Harlequin edition was published the next month and is technically a reprint because it was printed from the same plates as the McGraw-Hill edition.
There are two variants of the Harlequin printing. The first is identical to the McGraw-Hill with the title Royal Story on the half-title and title pages and the odd sequence title page, blank, copyright page, half-title. The other Harlequin variant has the correct title and correct sequence half-title, blank, title, copyright. I don't know if there is a McGraw-Hill edition with the corrections. The other difference between the Harlequin variants is the cover title which is first red and then red/blue in the second.
