Altemus published a number of publisher’s series in the 1890’s and early 1900’s. These series consisted of numerous reprints of poetry, fiction, the classics, essays, etc. Each series had a unique decorative cover. These series’ covers changed every year or so for the series which were long lasting.

The Diplome D’Honneur Series was published only in 1902 and only had 50 different titles. See http://henryaltemus.com/series/series76.htm.
Thus this is perhaps the rarest of the Altemus publisher’s series. What makes it interesting is its cover. It is half-white vellum on the left with a decorative pattern. On the right half of the cover is brocaded satin in one of several colors. Altemus only published this series with satin covers. I suspect it was to give the consumer a greater selection of decorative books to choose from. The books originally came boxed.

Today I am adding two new cover pictures for this series to the database. Five different satin covers have now been seen.
