Vintage PEPSI FREE Working Wall Clock Octagon Shape NO Light or Backing

Description

This is a mid-1980's vintage wall clock advertising the, new for the time, Pepsi Free cola which was caffeine free. Clock measures just shy of 20" tall and 13-1/2" wide.  Clock mechanism works fine with one AA Battery (not included). There is what looks to be price sticker residue on the face of the clock that could probably be removed with GooGone.
I believe this used to have a light mounted in the back with a solid back, but not positive.   Pepsi Free looks to have a protective plastic over it and not sure if it was to be removed originally when new or was to be pemanent and is now bubbling in places?  There is one place where someone tried to remove some, about a quarter in size.
