On Wednesday I got three postcards: one from Germany, one from France and one from the USA.
The card from Germany shows various views of Mülheim an der Ruhr. Mülheim an der Ruhr is a big city in North Rhine-Westphalia. In 1966 became Mülheim an der Ruhr the first city in the Ruhr District without coal mines. Famous museums in Mülheim an der Ruhr are the art museum (lower left corner), the museum of the past history of the film (lower row second from left) and the Aquarius water museum (upper right corner).
