Old Switzerland letter cover 1971.

Upper images show an envelope, cover with stamps and postmarks from Switzerland. Sent on 13 April 1971 from Lugano to Dresden, Peace Road Nr. 18th
Dresden was then still part of the German Democratic Republic.
The stamps on the front of the envelope shows the date of April 21, 1971.
It may mean that he on that day of the GDR censorship was released?
The letter is very nice with various Helvetia stamps franked with very clear postmarks. A little historical document.
