I have discovered a new word: "ghostsign".  I think I may pursue other such signs for future blips.
I have no idea how long this sign has been here; I suspect pre WWII?  Not much of this part of Coventry survived the Blitz, so it's a blip worth capturing.  Also, personal reasons for this: I briefly lived on this street as a very young student back in the summer of 1987 - happy carefree times.
