There is no date given in this George H. Doran Dulac edition, but a few book sellers indicate this edition comes from around the 1920s.
This Doran Company edition, regardless of the true age, is in really good condition. There might have originally been a dust jacket that went with it…I can’t find much information either way about that. But the pages could be new and I wouldn’t find much cause to disagree. The color plates of Dulac’s illustrations are in fabulous, vibrant condition. Dulac’s art is fantastic and the colors in this edition do the work so much justice.
Update 06/2023: Updated the layout, added pictures, and tweaked page copy.
