Here is a 1994 Williams Flintstones playfield.   We really did not want to fix this playfield.  The playfield had a lot of damaged inserts.  We tried to save some of the insert artwork by feather sanding out the edges.  We quickly discovered that some of the insert artwork was fixed before by some mylar printed sticker artwork.  We removed all the insert stickers and the large center inserts were totally blank (gone).  The main center insert artwork had to be hand painted and airbrushed.  No insert stickers were used on any of the inserts.  No stickers or overlays were used anywhere on this playfield.
