I just returned from my city trip to Vienna and during my trip arrived many postcards. Among the cards are four German cards.
One of them shows the Molkenhaus near Bad Harzburg in the Harz. The Molkenhaus was built in 1822 as stable and is now used as hiking destination with restaurant. The Molkenhaus also offers to feed deers.
My mum send the card to me when she recently hiked in the Harz.
Glücksburg Castle (from set of two) (issued 02-01-2013)
On the backside my mum also affixed the stamp of the Harzer Wandernadel No. 169 (Molkenhaus).
