Lem Motlow, Jack Daniel's nephew had one of his distilleries right here in B'ham. This downtown "ghost sign" on the corner at 2nd Avenue North seems to be in good condition. I'm glad my city is preserving these signs!
Wikipedia is back up and running and gives this definition of a ghost sign:
A ghost sign is an old hand-painted advertising signage that has been preserved on a building for an extended period of time. The signage may be kept for its nostalgic appeal, or simply indifference by the owner.
I thank my friend, NY blogger Daryl for tipping me off to the term when she visited me here last summer. Now I'm on the prowl for more!
