Bally Skateball Backglass Artwork (2 Piece Set!)

This is a incredible piece.  This is a original high quality concept drawing that was used to design the Skateball Pinball Backglass.  This was hand drawn by well known pinball artist Kevin O’Connor.  The quality of this piece is off the chart. Plus you get a revision piece that was never used and is seen for the very first time in decades!  Very few of these original drawings come up for sale as there is only one for each pinball backglass.   This about actual backglass size.  I have priced this piece at what I think it should sell for, but I do take offers on each item that I list.  These pieces are mounted on heavy duty postboard and will frame real nice.   A very great iconic piece that would be the pride of any Skateball or early Bally pinball collector.  Christmas is not that far away and this would be the absolute over the top gift to a lucky pinball collector.
