My daughter Sara's house is a farmhouse built in the 1860s, one of the first homes in Miamisburg OH.  We have tried hard to keep the look of the original while containing all the old lead paint and (apparently no asbestos since the pipes were not wrapped).  In removing some paneling (installed sometime after the house was at least 100 years old) we found some wallpaper.. only tiny scraps were still visible with a pattern, and one flower appeared intact enough to create a pattern.  This is a simplified stained glass pattern from that wallpaper, likely installed sometime in the early 1900s.
