Williams Spellbinder Backglass Black Line (Unreleased title)

This is the blackline drawing for the Williams Spellbinder Pinball Backglass.   This is part of the set that would have been used to produce the backglass.   The other colors were not found which is strange as we normally have all the colors for a artwork piece.

This is a very rare title.  This game was supposed to be the sequel to Hyperball.  Hyperball sold so poorly that this title was cancelled during development.  A color backglass and playfield proof does exist as the pictures are on Pinside.

Very few of these original drawings come up for sale as these are unique one of a kind sketches.      A very great iconic piece that would be the pride of any Bally pinball collector.
