This publisher’s series was published between 1896 and 1910. During this period of time the decorative cover was changed thirteen times. Almost every year a new cover format was introduced. Each new cover generally was seen with new flowers, decorations or pictures within a constant cover template.

The book below which is newly entered into the database depicts the 1899 cover. The left side of the front cover is constant for all 1899 Petit Trianon books. On the right half of the cover, various floral and decorative patterns have been identified.

This new cover is the 26th different 1899 right half cover that I have seen.
