National Book Auctions, located in Ithaca, NY, held a recent auction with a wide assortment of automotive, historical, exploration-related books and ephemera on offer along with a collection of important signed material.

Of particular note was John Hannig Speke's "What Led to the Discovery of the Source of the Nile" (1864). This antique volume is a scarce history of the explorer John Speke's search for the source of the Nile River.

Frontispiece: 'The Speke Escape'

The work is illustrated with a frontispiece portraying Speke's escape from the natives, a fold-out map of Somali Land, listing the location of the various tribes, and a two-page map, with a red line showing the expedition routes. The book fetched a hammer price of $1,000 (plus buyer's premium).

Also featured was a signed late printing of Harper Lee's "To Kill a Mockingbird" (1960). The classic work was signed by Harper Lee on the front free endpaper and inscribed "To Eddy With My Best Wishes, Harper Lee." This one-of-a-kind find realised a hammer price of $650.
