"this cover is a Plusbrief, a Plusbrief-Individuell
it is a "self-made-stamp" and the cover has a limited edition with 100 items.
One rule of German Post say: No special Postmark on Plusbrief, only daypostmark - and your cover has a special postmark , these are unusual and I do not know why"
nice "plusbrief" in limited edition and great postmark (very RAR for plusbrief).
