In the past couple of weeks, we've been looking at mailboxes along Water Street. The first was in the 800 block, just east of 1st Avenue. Now we're finishing this part of Water nine blocks east, in the 1700s, just west of Campbell. (There's more just east of here — as well as more sections of Water, here and there, including the last one I've found which is past Craycroft. I'm hoping to catch all of Tucson's creative mailboxes by some year in the future...)
Though I couldn't find any photos that look much like it, this design reminds me of something I'd find at a dock (without the mailboxes, that is). I found it May 20th on... where else? Water Street. The boxes are addressed
1716 and 1710.
