Four of the nine cards that arrived during my absence are from Germany.
One of them shows an illustration of the opera The Flying Dutchman. The Flying Dutchman is an opera by Richard Wagner. It premiered in 1843 in Dresden. It is one of Wagner's operas that is played at the Bayreuth Festival.
I got this card a few weeks ago in a cover.
