The flyer incorrectly states that there are five thumper bumpers (pop bumpers). We previously showed the designer was Harry Williams. The manufacturer's original playfield drawing (not shown here) is stamped ORIGINAL, is dated 6/19/59, revised 9/25/59, and is signed by (Harry) Mabs. The manufacturer's Tool Room copy of this drawing (also not shown here) is stamped MASTER, drawn 10/14/59, and dated 10/22/59.
