Today I got a nice postcard from Germany! The postcard features multiple views along the River Rhine. We see views of three picturesque castles, Burg Rheinfels, Burg Maus, and Burg Katz. Burg Katz ("cat") and Burg Maus ("mouse") supposedly got their names because they were owned by two rival brothers. The card is an official Postcrossing card, DE-3148698. A nice matching stamp was used! Thanks Pythagora!
