On Thursday I got four postcards from Germany.
One of them shows Titian's Emperor Charles V from the collection of the Alte Pinakothek in Munich. The Alte Pinakothek is an art museum opened in 1836. It shows the Old Masters' paintings from the Bavarian State Painting Collections, one of the most famous collections of its kind.
I bought this card recently in the Kunsthalle Hamburg.
With a matching stamp:
