A huge rarity - until recently the existence of occupation patterns was doubted at all.
This was probably due to the fact that typical checkout patterns (with consecutive numbering) were not prepared during the occupation period. However, the production process involved the printing of technological and acceptance patterns, and that is what we are dealing with here. The zero numbering confirms that this is still a pre-production issue.
Very good state of preservation for this type of pattern.
Sporadic pieces of such patterns appearing on the market are usually very damaged, as they came to the collector's market probably after the destruction of the factory during the Warsaw Uprising. This piece is without loss and without overdressing. Only a few vertical fracture lines centrally and a fracture in the left margin are visible through the folder. Broken upper right corner and traces of annotation on the reverse. Other than that, no comments. Presentation very good.
