Before I ask my question, I would like to wish everyone a Happy and Healthy New Year.
My question is about this postcard. The postcard is posted on the 04.08.1922. with stamps on the front. The 15 kronen stamp would be the right postage. Then there is the 2 kronen greyblue stamp with the diagonal placed cancellation Graz 4. Question 1: Is there a valid Postal reason for this stamp to be on this postcard? Question 2: What type of cancel is the graz 4 cancel. Thanks for your thoughts. Kind regards, Johan.
