The first appearance of MORNING STAR was as a serialized novel, published in The Christian World News of the Week between October 1909 and March 1910.
McKay, Scott, and Whatmore claim that Cassell and Company published the first edition in book-form in London on March 11, 1910. Apparently 13,500 copies were printed, with 3 illustrations by A.C. Michael, 2 in color. Ads at the end of the book are dated-coded 1/10 (January 1910).
Higgins claims that Cassell paid ÂŁ450 ($76,000 in 2020 dollars) as an advance for publication in book-form.
Longmans, Green and Company published the first edition in book-form in New York on May 27, 1910. The same illustrations as found in the Cassell first edition are included in the Longmans edition. There are no ads at the end of the book. McKay and Scott both agree on the New York publication date.
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
