Here is a new advertising flyer for this series of fifteen books. The one sheet advertisement which is 9 x 3.25 shows an example of a book cover and lists all of the books.

This series had a number of cover pictures all of which were made from different linen swatches. See http://henryaltemus.com/series/series57.htm.

The books initially came in labeled boxes but later some were issued with dust jackets. Frequently there is confusion between these books and those from the Young People’s Library. This is because the interiors of the books of the same title are identical including the title page which states “Young People’s Library”.

The date of publication can be confusing also since Altemus often put the copyright date on the title page. This series’ books can be dated by studying the ads in the back of the book. The series was published between 1908 and 1926.

Shown below with the flyer are cover, box and dust jacket examples.
