The first appearance was as a serialized novel, published by THE AFRICAN REVIEW from July 4 through November 7, 1896. Charles Kerr created 21 illustrations for this serialization.
McKay, Scott and Whatmore claim that Arrowsmith published the first edition in book-form in London on October 29, 1896. Apparently 20,000 copies were printed in variant bindings, none of which were illustrated.
Longmans, Green, and Company published the first American edition in 1896, but with only 19 of Kerr's illustrations. Ads at the end of the book are not dated. McKay and Scott both list December 8, 1896 as the publication date.
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
I do not own the serialization of this novel in THE AFRICAN REVIEW, but did manage to locate the two illustrations missing from the first American edition.

This is an image of the exceedingly rare original 1896 dust jacket for the first American edition. Sadly, my collection does not include this original DJ.
