unused Worldwide, 20th, massive holding of many tens of thousands of mostly unused stamps neatly sorted in 18 large stockbooks, incl. some 19th, but vast majority are 20th, several stockbooks are thematic in nature (U.N., Brussels Fair, Rotary, IGY, UPU, etc.), others incl. individual countries or are sorted by countries alphabetically, contains many better useful stamps, souvenir sheets, some artist die proofs, souvenir cards, etc., also some items on retail cards in manila envelopes, etc., the stockbooks do incl. some never hinged material, but, unfortunately, also contains a fairly significant percentage of material with small tape stains (done previously to keep them properly positioned in mounts) thus the lot ranges from good-very fine, very high catalogue value, but the lot must be inspected and is not subject to return for condition problems, there is still, however, much salvage value throughout the lot
