Bally Kings of Steel Back Glass Pencil Drawing

This is a original pencil concept drawing set  that was used to design the Kings of Steel Pinball Backglass.  This is not drawn to about 75% scale.

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