This was taken at the old City Bank building on East Capitol (previous picture), which has now been converted into a private residence. I thought it was very clever that they use the former Night Deposit Box as their mailbox. The owners finally had to put a sign reading “mailbox” on it because no mail carrier except the regular one could ever find it.
