well done mate.
the artwork on the MYSTIC backglass, has artwork very stylish like TALES ARABIAN NIGHTS and THETRE OF MAGIC had designed years later. You can definately see that influence used years later. probably the same artist ?
also, the eye with the pyramid,which is on the top of the playfield, along with the pop bumper cap designs, is also a prelude to what was later used on TWILIGHT ZONE.
its good to see how those ideas, all on the MYSTIC machine, were later used to great sucess with BALLY'S later releases.
Cant wait to see these 2 x machines all done up. 
Mate, the "ALL SEEING EYE" or the "EYE OF PROVIDENCE' .. also "EYE OF GOD" has been around for thousands of years... its also on every US$ bill. Its quite commonly used when people want to depict something of a mystical nature. The eye inside a pyramid or even a triangle is one of the best known ancient symbols....
.... LOl- just had to clear that up
