Williams licenced to Segasa.
Segasa artwork outlasted Williams and remains pristine for much longer
 Playmatic machines are always in good cosmetic condition.
Zacarria games always have great condition artwork.

I honestly believe that the Europeans had a much better process when it came to the artwork.

I love the artwork on Playmatics - this one though is really 10 - 15 years behind anyone else with its angular artwork or "pointy people" as it is sometimes described.
 I just cannot bear to look at the square bumper caps on Playmatics though... then again, i dont like 70's GTB caps either
