This idea comes from The Pen Pal Project.

I like all the little details of buildings, mail slots are one of those. They’ve become obsolete here. Mail will no longer be delivered door to door at all in Ontario soon. I have a beat up looking mail box outside my front door. It began as black and new, was spray painted a few different colours (bronze, and green another time). No point in replacing it. Once the mail stops coming to the house the only thing left will be junk mail delivered door to door and the local newspaper. The newspaper delivery (and the odd courier package) is how the mail box got it’s beat up look.

I don’t know about you, but with all this letter writing, I’ can’t help but notice letter boxes, mailboxes and mail slots every where!!
