After finishing the series of Aunt Jane's Nieces books, L. Frank Baum began the Mary Louise series, using his Edith Van Dyne pseudonym. Baum took the title character's name from his favorite sister - there was also a Mary Louise in the book Annabel.
The Mary Louise books have the plainest bindings of any Baum title published by Reilly & Britton. Maybe the publishers felt that Edith Van Dyne was such a popular author, there was no need to spend money on attractive covers!
On the left I'm showing a first edition in dust jacket, a first without the jacket, and a Reilly & Lee edition in jacket from the early 1920's. The original dust jackets use the same image on all the titles, a flock of bluebirds in flight. The series was given the additional title of The
Bluebird Books, for no apparent reason that I know of, unless it was to justify the bluebirds on the jacket! As you can see, the later Reilly & Lee editions used a new jacket design - once again the image is the same on all the titles, but the color in the background changes.After Baum's death, the series was continued using another author - just as the Oz series was continued with Ruth Plumly Thompson.
