SBZ No. 52atx DDDII unit of 8 TLC, certificate Jasch BPP!!! Unique!!!

A variety not known in catalog in canceled condition. In such a large unit from the sheet edge, a figurehead for every SBZ special collection!
Interestingly, the partial printing failure of the gray color on field 4 mentioned in the certificate is missing exactly diagonally, so that it can be assumed that a sheet of paper was formerly on it.
It is quite certain that the only partially printed sheet was initially sorted out in accordance with the regulations and then later used again for overprinting with a slightly darker color due to a lack of paper.
Unique piece of evidence to the emergence of this variety!
