Czechoslovakia. ★★/★. Thousands of stamps, an important mint holding, housed in one crammed-packed volume, beginning with an extensive range of a few hundred issues of the 'Posta Ceskoslovenska 1919' overprints, followed by further hundreds of occupations and regional issues, e.g. Romania 1919, French occupations. Transylvania through to unlisted overprints, Lajtabansac and much more back-of-the-books incl. Baranyas etc with plenty of unlisted. An astonishing lot that would delight any dealer in this area, almost impossible to assemble again, it has so much substance.
