Did you know maps on stamps is a thing, has been for years? And did you know there is a CartoPhilatelist Society? Surprising sub-cultures under every rock. I really like this trio of German maps, and the cancellation marks only add to their charm. Here’s the story: “The town of Ingolstadt was first mentioned in a document of Charlemagne in 806. In 2006 Germany issued a stamp to commemorate the 1200th anniversary of Ingolstadt, picturing a portion of a map published by Philipp Apian (1531-1589) in 1563,” says Dan of dans.topicals.com, a website with zillions of beautiful and amusing maps on stamps, including a section of map-on-stamp fails. Next up, maps on the heads of pins.
