Sometimes you see things you don't expect to, and this was one of those times, during a Christmas shopping expedition to Liberty earlier this week.  I'd noticed the stained glass panels in some of the windows there before, but not this one behind a till point on the third floor.  Perhaps the glass was especially fragile, but it looked like it hadn't been touched for years, while all of the surrounding panes were, well, a lot cleaner.  While I waited to pay I suppressed my urge to buy some Skin Laundry cleansing cloths to wipe away the grime myself.
