Here are books from a series. I am just unsure which series they are part of. I have seen three titles in two different colors with this same cover pattern. Clearly these books are part of a publisher’s series. Because of the Henry Altemus imprint we know the book is a post-1900 published.

The possibilities include:

1. #48 Beauxarts Series
2. #115 La Belle Fleur Series
3. #118 L’Art Nouveau Series
4. #180 Vademecum Series

In order to determine which series they are part of, I will need to get either a boxed book or a dust jacket which undoubtedly will have the series name on it.
