MOON OF ISRAEL first appeared as a serialization in The Cornill Magazine, January 1918 through October 1918. This serialization has no illustrations.
McKay, Scott, and Whatmore claim that John Murray published the first edition in London on October 31, 1918. The ads at the end of the book are not dated. McKay and Scott claim that 10,000 copies were printed.
Higgins claims that Murray paid £250 ($24,000 in 2020 dollars) for the serial rights, and £500 ($49,000 in 2020 dollars) was advanced for publication in book-form. In addition, "John Murray agreed to give Haggard a half-share in the copyright of JESS which had been acquired when [he] published Smith, Elder & Co.'s business."
Longmans, Green and Company published the first American edition on November 14, 1918. McKay and Scott both agree on the publication date in New York. The American edition has a frontispiece illustration by Enos B. Comstock. The ads at the end of the book are not dated.
A few newspapers serialized this novel in 1919, with Edmund Frederick illustrations.
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
The ads at the end of the book prominently include on the first page an ad for JESS.
Note: I have yet to see any John Murray edition illustrated with 12 Maurice Greiffenhagen illustrations, though the publishers of the British first edition of JESS (Smith, Elder) did publish in 1896 an edition with 12 Greiffenhagen illustrations.
The seocnd printing is thinner than the other two.
