While the backglass design is very similar to Williams' 1960 'Black Jack', the playfield layout more closely matches Williams' 1958 'Club House'. We previously showed the designer was Harry Williams. The manufacturer's original playfield drawing (not shown here) is stamped ORIGINAL, dated 12/1/59 and is signed by (Harry) Mabs (and drawn by him, but only the one signature). This drawing was also used as the Tool Room Copy because it is marked with all the usual routing jig info and completed on 12/14/59 with the note "Made from Clubhouse jigs."
