New York, J.S. Olgivie, 1903. First edition, first impression. Hardback. A very good copy. A note suggests: Christianity vs Socialism, but I prefer the fact that it contains civilisations on other planets in the solar system! Spine a touch faded, with a bit of rubbing. Spine tips bumped and worn, with a scuff to the upper spine. Some pencil notes, a seller's stamp and an ink inscription with some foxing. [10475, Hyraxia Books].
