zumstein briefmarken

Cover of Zumstein’s Briefmarken Katalog 1935. I also have 1932, 1945 and 1956. Each illustration in the book is scratchboard, maybe 3/8" tall. Ridiculous amount of work to do these illustrations. Average page has maybe six illustrations, some have up to 20… Hmmm. 500 pages (1932) + 546 (1935) + 882 (1945) + 1284 (1956) = 3212 pages would definitely be over 20,000 spot illustrations. Got all four books for $20.
