The November 27, 2015 entry 2013 North Swan Road shows a mailbox along this busy street. When I stopped by on February 9, 2021, to take photos of the mailbox and building just south (see next week's entry), I noticed that the mailbox at 2013 had changed.

But there's more. I glanced at the buildings on the land behind the mailbox and saw murals. There are photos in today's Tucson Murals Project blog entry, Zooming in on 2013 North Swan.
