"A pure Zulu story"
First appeared as a serialized novel, published by THE ILLUSTRATED LONDON NEWS from January 2 through May 7, 1892, and this serialization contains 32 large and excellent illustrations by R. Caton Woodville.
McKay, Scott and Whatmore claim that Longmans, Green and Company is purported to have published the novel in New York on April 30, 1892. Longmans supplied 23 new illustrations, on plates, by Charles Kerr, electing not to use any of the R. Caton Woodville illustrations. The American first edition has no frontispiece.
McKay, Scott and Whatmore also claim that Longmans also published an edition in London on May 9, 1892, with the same illustrations as found in its American edition, but with a frontispiece, and that 10,000 copies were printed. Ads at the end of the book are dated-coded 2/92 (February 1892).
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
I do not own any of the books pictured, unless noted.
