This building's painted wall sign for National Auto Glass still displays the very old style of telephone exchanges. Note the number is "MA2-4849." With a little Internet digging, I found out that "MA" was "Main" in Tucson - in use until the 1960's.
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
