Last Saturday I got three postcards from Germany
One of them shows the Princesses Group. The Princesses Group is a sculpture of the Prussian princesses Louise and Frederica created by Johann Gottfried Schadow. It is now shown in the Old National Gallery in Berlin and is considered to be a masterwork of the early Neoclassicism.
I bought this card when I was in Berlin earlier this year.
With matching stamps:
250th birthday of Johann Gottfried Schadow (issued 08-05-2014)
Treasures of German Museums (issued 11-10-2018)
with First Day Special Postmark
