1969/1981 (ca.), duplicated accumulation in large box with mostly IMPERFORATE single stamps, complete sets, sheetlets and miniature sheets but the large part are PROOFS (progressive, collective or composite) in different combinations and some other unusual varieties, attractive THEMATIC ISSUES etc. with many prepared for individual sale sorted into glassines and priced in US$, mint never hinged and a great lot for country or thematic collectors or resellers with a very high retail value – PLEASE INSPECT!
