This gorgeous card came to me from Germany.  I am guessing that the music is by Mozart, anyone have a educated guess. I did visit the design website, Susy Card, but couldn't find any postcards.  I've changed my profile at postcrossing and asked senders to include a book recommendation on the postcards they send me.  .  I received my first one on this card for Level 26: Dark Origins by Anthony E. Zuicker.
