Illustrierter ausführlicher katalog über deutsche postfreimarken
This is a German-language illustrated catalogue of postage stamps, compiled by Hugo Krötzsch and published in Leipzig in 1896 for stamp collectors. Its pictures are plain black-and-white wood engravings of objects rather than stamps: book-binding and press devices, a self-binding album shown in hands, and watermark diagrams, offering a designer ready examples of mechanical, technical line drawing.
