I too would buy a stamp just because of where it was cancelled. Keep in mind a 1 cent stamp can become a $10 stamp or more with the right cancellation.
I agree Phil. I find Austrian postmarks fascinating particularly when they reflect national boundary changes like this one. Laibach is the German name for Ljubljana in Slovenia.
As a "worldwide" stamp collector i get a lot of enjoyment out a simple thing like a minimum catalog value stamp with a nice town cancel.
