In this series the Format 2 books have a decorative pattern on the left(vellum) of the front cover that has been seen in white and red. On the right of the front cover various flowers are depicted. There are several Altemus series in which the same flowers have been seen. In all I have noted 16 different flowers as possibilities for the right half of the front cover here. Whether all 16 (which are shown at http://henryaltemus.com/series/series110.htm) were actually used in this series is not yet known.

The flower here-Lily of the Valley – is the 9th different flower for this format (white vellum) that is included in the data base. The red left front cover books are distinctly less common. So far I have only seen 3 different flowers on those books. Including the red and white covers, 11 different flowers have been noted.
