This map card is of the 'German Clock Route' in the Black Forest.
It's about 320 km long. On this route you'll find museums related to clocks and of course many clock factories. I'd love to go and see all the fascinating clocks and beautiful scenery and maybe even buy a nice cuckoo clock to bring home.
Thank you to Violet from Germany, who sent me this cool card for the January RR.
Nice big stamp. Looking at it makes me hungry for strawberry short cake.
