L'inconnu= The unknown
L'inconnu, published in New York by Harper in 1900 and written by the French astronomer Camille Flammarion, is a parapsychology and spiritualism book bilingual in French and English. The first picture is an oval laurel-wreathed emblem with a torch and Greek lettering, and the second is a set of paired drawings contrasting original objects with reproductions, showing a designer how such comparisons can be laid out as a clear grid.
