If any of you guys are in Lincoln go and have a look at the old Corn Exchange building in the middle of town. It's currently being "redeveloped" (tarted up) and there are some really nice big old painted advertisements on the interior walls. They must be 10 feet square or more and they are mainly for local businesses, animal feeds etc. You can just glimpse them now that the upper storey windows have been removed, they must have been hidden for 70 odd years or more but they still look fresh as the day they were made. Check them out before they get covered up again or destroyed. I'll try and get some photos, but you can't get very close unfortunately...
