I saved this cut square years ago only because I like the postmark:

Little did I know at the time that in 2011 it will become a discontinued post office (DPO):

I wonder if they would honor a request for a last day of service postmark? As a walk-in, I know they would be obligated to provide a hand cancel upon request, but not sure if they would do it by mail. Has anyone tried it?
