This postcard with Kitzbühel cancels and a 10 heller Notgeld has cachets from two local huts; the ski club; and the mountain rescue! There is a standard Chamois cancel dated 15/3/1954 on the 5g stamp, but there was no such rate at that date (even Inland Printed Matter was 30g) and it can only have been applied to obtain the cancellation. I'd suspect it's a fundraising, or even a fun, item.
