Handwriting on the wall

Big surprise one afternoon when we were jackhammering through a few layers of wallpaper and found this handwriting on the wall!  Just below the ceiling line at the top of the stairs is this writing by one of the builders, "Ed Conradson the painter".  It was a pretty cool surprise to uncover this signature after 115 years; just waiting under the wallpaper to finally see the light of day.  Seems it was written using a carpenter's pencil in 1902.
