GDR 1953/1990 - Collection of DDR record defects, about 90 pieces, all stamped - Michel XXL

see photos - everything is shown roughly, a very extensive East German DDR collection of about 90 misprints/plate faults, all stamped from an estate with a gigantic Michel value (at an average of €50 that would be €4,500), including repeatedly also better sought pieces with Michel value over €100, including Block 10 PF III already checked (€400) and Block 12 IX (€450); according to my checks all are only plate faults per Michel!, in the course then many PF in units so that a field determination is also possible; shipping takes place on one album page as pictured.
