For the most part the cover changed yearly in this series (http://henryaltemus.com/series/series141.htm).

In 1897 there were numerous decorative patterns on the right half of the front cover. The left half of the cover was the same in all of the 1897 books.

Here is a new cover design for the database for the 1897 books. With this cover there are now 12 different cover pictures in the database.
