McKay, Scott and Whatmore claim that Hutchinson and Company published the first edition in book-form in London on January 4, 1929. According to McKay and Scott, 3,500 copies were printed, but Whatmore claims 8,000 is the number of copies. Nevertheless, the first edition is without illustrations, but with ads at the end of the book dated Autumn 1928.
Doubleday, Doran and Company published the first edition in book-form in New York on May 17, 1929. McKay and Scott both agree on the New York publication date, and claim that 3,500 copies comprise the first printing. There are no illustrations, nor ads at the end of the book.
The Ryerson Press published the first edition in Canada, likely also in 1929.
I do not own any of the books pictured below, unless noted. I do own copies of both the British and American first editions.
The British first edition original dust jacket
This DJ is very rare and I do not own a copy
So-called "Cheap Edition" with original dust jacket. Whatmore claims that the pagination of this edition is no different than the first edition.
