A Dream Story
According to McKay, Scott, and Whatmore, Henry Holt published the first edition in New York on October 16, 1911, and Longmans, Green, and Company published the first edition in London on the same day. Ads at the end of the Holt edition are date-coded "vii' 10" (July 1910). Longmans did not bind any ads into the textblock, but did insert a laid-in card of ads, which are dated October, 1911.
The Holt first edition comprises only 1,500 copies, whereas the Longmans first edition is composed of 5,000 copies.
W. T. Horton and H. M. Brock each contributed six full-page illustrations to the Holt and Longmans first editions.
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
