GDR stamp collection

Lot 9029 limit € 180

mint never hinged, probably the complete collection over the period 1949-1990, with the sought-after top values: Marx blocks, Debria block, German-Chinese friendship, Academy set, Engels block, large block "15 years DDR" etc., over long stretches more than complete and probably in duplicate, since many issues stamped behind it, unchecked behind transparent pockets in two thick lighthouse form albums
