The manufacturer's original playfield drawing (not shown here) is stamped ORIGINAL, dated 4/1/59 signed by Harry Mabs and drawn by him, too (his name appears twice). The manufacturer's Tool Room copy of this drawing (also not shown here) is stamped MASTER, drawn 7/16/59, completed 7/28/59, revised on 10/8/59 with a Mabs approval signature with that date. Duncan Brown comments on Mabs' handwriting on the ORIGINAL drawing:The notations and such (the free-hand things) are suddenly in very-old-man writing style. Letters are very carefully drawn in a very shaky hand. I�m beginning to think his exit from Williams the following year was from age or other medical issues. But suddenly he�s his own (and Harry�s!) draftsman, what is up with that?
