The Love and Friendship Series (http://henryaltemus.com/series/series127.htm) is multi-authored, multivolume series of fiction, poetry and essays that has five different formats. Several of the formats have different stereotypical designs (patterns) on the left half of the front cover and one of sixteen different flowers pictured on the right half.
The first format has been seen with eight different flowers on the right half of the cover and Format 2 with eleven flowers. Presented here is only the second flower seen on a Format 4 book. This is the Violet(2) picture.
Series #110 In His Name Series (http://henryaltemus.com/series/series110.htm) has the same five formats as the Love and Friendship Series. So far in that series I have only four different flowers for Format 1, eleven flowers in Format 2 and three in Format 4.
