The first appearance of THE HOLY FLOWER was as a serialized novel, published in The Windsor Magazine and New Story Magazine December 1913. The Windsor Magazine serial ends in its November 1914 issue. The Windsor Magazine serial contains 16 Maurice Greiffenhagen illustrations, 1 in color. The New Story Magazine serial is reported to end in its June 1914 issue. I do not know if this serial was illustrated, but two of the covers appear to have to do with this novel, and the covers were illustrated by N.C. Wyeth.Â
According to McKay, Scott, and Whatmore, Ward, Lock, & Co. published the first edition in London on March 31, 1915. All 16 of Maurice Greiffenhagen's illustrations are present, though all are black and white. The are ads at the end of the book, but they are not dated. McKay and Scott claim that 14,000 copies were printed.
Longmans, Green and Company published the first American edition on March 31, 1915 with the title: ALLAN AND THE HOLY FLOWER. McKay and Scott both agree on the publication date in New York. The American edition only includes 12 of Michael's 16 illustrations. There are no ads at the end of the book.
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
The March 1914 issue cover mentions that the serial continues in that issue, but the April 1914 issue cover does not mention HRH or The Holy Flower. Since I do not own any of the New Story Magazine issues, I cannot confirm if the serial continues into the June 1914 issue or not.
