Octavo. 250 pages and 2 plates. A cheap pre-war production. The book is in pretty good shape with slight ingress of old damp staining to the endpapers. The jacket has seen better days. It is damp stained and grubby to the rear panel. Internally the book is clean and without names or inscriptions. Bound in original red cloth boards. A weird tale of "white indians", priests, a lost cult, gold, flying machines, aerial combat, pyramid, and the hall of death. All set in the wilds of the Yukon. Wow!
