Here is one of the very scarcest Altemus books. In the 1890’s Altemus published a few books in paperback. These books are quite rare. In 1897 the first Altemus edition of Klondike by L. A. Coolidge was published in both wraps and hardcover. Here is the book in wraps. A later second edition was published in hardcover.
