Heritage Calling published a nice essay on the post boxes of England. I never tire of seeing these bright red (and sometimes green or gold) boxes in their distinctive shapes. I tend to love mailboxes of all types. There's something about it being a portal of potentiality that I find thrilling. It's as close to magical as I've found. If you like reading about English post boxes, I have a few more links for you to earlier blog posts.
P.S. Image from the Instagram of L.W.A. member Suzy. She's got lots of great photos and many pictures of post boxes and mail.
