Help find the postmark (Not stamp) Deutsche post
That is not a stamp, but a stampel. It is placed by Deutsche post office. Look at the photo - on the top of the card the left round one is placed by my home town post office, the middle one (not round) is the one in question and the right round one is also placed by Deutsche postoffice. The one in question is named in Deutsche Post “Sonderstampel” and it is devoted to some interesting fact or event. I can read “50Jahre MZ”
