Publisher's advertisement for Heroes of the Dark Continent and How Stanley Found Emin Pasha by J. W. Buel, published by the Historical Publishing Co. in 1889, four pages, 11.25 x 16.5, featuring a descriptive text with ten illustrations, as well as a price list and subscription information. The advertisement promises tales of "hostile men and ferocious beasts," "wild tribes," "wondrous animals," "explorers, adventurers, hunters and missionaries," and "splendid discoveries." It states: "The expedition of Stanley, carrying us over a period of three years, is made the crowning feature of this grand book, and without invidious comparison we may justly claim the description, as here given, the most exciting, captivating, instructive, and altogether the most fascinating narrative that has ever been published." In very good to fine condition, with intersecting folds and moderate handling wear. In addition to an overview of African history, customs, and geography, Buel's sensationalist book provided an engrossing account of intrepid explorer Henry Stanley's quest for colonial governor Emin Pasha in 1886.
