The card shows one of the most beautiful opera house in the world: Semperofer in Dresden, Germany.
Semperoper was built in 1841. The acoustics and the orchestra, the Staatskapelle, are marvelous. Its history saw many operas of Wagner and Strauss having their first nights there. Nowadays productions are of lower quality and follow the German "Regietheater" fashion.
This is an illustration for H C Andersen's fairytale "Nukku-Matti" (1940) drawn by Rudolf Koivu (1890-1946). Annamari wrote me this lovely card and told me Koivu is one of the best-loved illustrators in Finland:)
But unfortunately, I googled and googled but found nothing explaining Nukku-Matti in Chinese. Is it a name of a god??
But the card itself reminds me a traditional Chinese story of Mice's Wedding:D
