THE VIRGIN OF THE SUN : A novel of Incas
According to McKay, Scott, and Whatmore, Cassell and Company published the first edition in book-form in London on January 26, 1922. Apparently, 11,000 copies were printed, without illustrations, without any ads at the end of the book, but the last page is date-coded 1121 (November 1921). There was no serialization.
Higgins claims that Cassell paid £750 ($122,000 in 2020 dollars) in advance of publication in book-form.
Doubleday, Page and Company published the first edition in book-form in New York on May 26, 1922. A frontispiece by an unknown artist is the only illustration in the first edition. McKay and Scott both agree on the New York publication date, and claim that 7,500 copies comprise the first printing. There are no ads at the end of the book.
Grosset and Dunlap reprinted this title in America.
I do not own any of the books pictured below, unless noted. I do own copies of both the British and American first editions.
