A dazzling piece from the great Muhammad Ali's huge marketing push in the late 1970's and 80's. Designed by Harry Williams and created by Stern Electronics, this original 1980 pinball machine back-rack is signed by the legend "Muhammad Ali" measuring 3" in black marker on the glass. The piece itself measures 29" x 26" x 3 1/2" and still has the original back lighting intact but no electronics. It comes with the original instructional paperwork. The signature is rated 7/10 and the back-rack, the glass and graphics are in EX condition. Ali's face is shown six times on the glass. He surely was the Greatest!
