They haven't changed much over the years but eventually rust out and get replaced. The oldest one I remember was in the mountain community of Julian, CA, embossed with the manufacture year 1933. I think it was there until about the 1980s, so they sometimes have a good long run.

"Advance to St. Charles Place," only in this case it would have to say "Return to St. Charles Place".

The Mailbox. When I started with the Post Office Department in 1970, we only had one box in our city like the one in the picture (out of 100 or more collection boxes). Notice it has a lock instead of a slot for a key. Instead of inserting and turning the key to open it, You inserted a special flat key into a slot on the lock and it would pop open. Every Letter Carrier had to sign for the special key and the regular key daily, even though most never used it.

I see one piece of white litter along the curb.

"Let's dress in many layers and stroll under a parasol."

That U.S. Mailbox does indeed look like the one setting on the corner near my house at this very moment. Too bad we're not Timelords. We could crawl into it like Dr. Who's police box and visit 1910, then come back and get some KFC. I suppose I, myself, would look pretty suspicious wearing jeans and tennis shoes, and a teeshirt that reads "Bonnie and Clyde Death Death Car."

And not a scotty dog, flat iron, or thimble to be seen.

And one hundred and five years later the U. S. Mail collection box could still be in use somewhere.
