The is marginalia on this card that indicates a different year than the postmark. The postmark seem to be 1911, but let me know if you believe other wise.
I think you’re right to go with the postmark as it should be considered a primary source (created at the time of mailing) versus the handwritten dates which should be considered a secondary source as they could have been added at anytime :)
