All Altemus books either came within a box or with a dust jacket. Finding the early 1890’s books with a jacket is quite difficult.

Here is a book from Series #150 (http://henryaltemus.com/series/series150.htm).

This book (Hawthorne’s Scarlet Letter) was published in 1893. On the reverse of the jacket this series as well as the Altemus Library are shown.
