Die Projektions-Kunst
A German technical manual on projection and the magic lantern by Paul Ed. Liesegang, published in Leipzig in 1909 for lanternists, teachers and demonstrators of optical apparatus. The plates mix wood-engraved diagrams of light paths, mirrors and rotating shutters with catalogue-style views of brass and cast-iron projectors, offering designers labelled optical schematics, hatched instrument renderings and geometric disc figures.
