Two castles in this blog post!
The first is an offical Postcrossing postcard
I love this view of Corvin Castle
(set of 6, 2013)
Each stamp combines the image of a flower with
a clock from the Nicolae Simache Clock Museum in Ploiesti.
The time on the clock tells us when this particular flower blooms during the day.
Finally in my collection Neuschwanstein Castle
"Tag der Briefmarke"
