Bally Fathom Back Glass Pencil Drawing

This is a original pencil concept drawing set  that was used to design the Fathom Pinball Backglass.

This is a very early concept drawing.   We do not see a lot of these that came from very early in the development process.

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.
