On 8th October I got nine postcards: four from Germany, two from Slovenia, two from Singapore and one from Japan.
One of the German cards shows the Research and University Library in Gotha. The Research and University Library of Gotha is a library of the German State of Thuringia. It was founded in 1647.
I got this card a few weeks ago in a cover.
