Ultimo, an imaginative narration of life under the earth

"This is a scientific fantasy set forth in a curious document by a man of the future looking backward, and recounting the history of humanity's sojourn inside the earth on the eve of his departure from it. This mighty conception is illuminated by the remarkable drawings of Mr. Vassos, whose art is so peculiarly adapted to the projection of the human mind into these limitless realms." -- Dust jacket.
