Philadelphia, T.B. Peterson & Brothers, 1887. First edition, first impression. Hardback. A good copy only. Ex-library copy. An uncommon novel and an interesting marker in the sf canon being an early novel employing solid worldbuilding in a secondary world. Alas, it's ex-library and there are plenty of signs internally. Shelf label on the spine, endpapers have evidence of label removals, stamps on first three leaves. Hinges pulled and a little split. Boards a touch bumped. [9698, Hyraxia Books].
