GDR - An overcomplete collection in 7 Lindner foldless albums with cassette.

Apparently more than a complete DDR collection in 7 Lindner fold-out albums + cassette (new price far over 1000 euros just for the albums!). Many extras, Debria block 2x (1x without gum), then all block single stamps and often the composite prints, additional types and colors, Marx blocks with additional overprints, Schiller block 4x and so on. We have the first volume complete, then only a few pages of the rest depicted. A collection like few people ever see. Here the collector has added extras with a lot of care. All in very well-preserved condition.
