ALTBERUN to ZYROWA, a very large collection of Upper Silesia cancellations comprising hundreds of singles / pieces and filling three albums. The previous owner sought completeness and added ideal illustrations of all cancellations represented for easier reference. The individual items are of selected quality, with complete and clean strikes included wherever possible. Overall a collection which would be very difficult to assemble to this degree of completeness, ideal for beginners but also a source of discoveries for specialists and research-minded collectors
