London, Chapman & Hall, n.d. [1867]. First edition, first impression. Hardback. A very good copy. Inscribed by the author. O'Neil was best known for his artwork, but this foray into fiction has left a smaller but equally long lasting mark on Utopian fantasy. Boards a little rubbed and soiled, with some bumping. Hinge separated a little, but holding well enough. Small seller's sticker to rear pastedown. Illustrations by J. Gilbert [11239, Hyraxia Books].
