The Petit Trianon Series (http://henryaltemus.com/series/series143.htm) changed its cover format every year or two. Generally in any one year the left half of the cover had a constant decoration while the right half had any one of a number of flowers or other patterns.

In the 1903-1904 books there were four different covers. Each had a pedestal on the left. One was soft leather. The other three had the left sided vellum in either beige, pink or blue. On the right was one of 16 different flowers. The beige book is the most common while the leather, blue and pink are scarcer.

The book being added to the database today is the seventh pink one. There are already seven blue books and nine beige books in the database. The 1903-1904 books came in labeled boxes originally.
