Quoted from MikeO:Wizard appears to have been an Italian prototype game that was never produced. Luckily they did the prototypes.
Yes, the 5 Wows in the head/backglass.
Yes, 1971.
Apparently there are a handful of "Wizard" games out there. Ran across an Italian that actually has one. On the 1971 Wizard the 5 WOWs are the 5 Orbs floating in the blue plume.
A buddy of mine snagged a Wizard NOS glass off of ebay and I built a lightbox for him. (photo curtisey of AvidListener )
