The Cannuli Bros. sign in Philadelphia: WA2-2988 & WA5-4376
The Cannuli Bros. sign in Philadelphia has 2 Exchange Name Numbers. WA2-2988 & WA5-4376. I thought the WA probably meant something fairly generic, like WAshington. That would make sense since a Washington Avenue is nearby. On the other hand it it might actually stand for WAlnut, the name of another Philadelphia Street.
