I love the art on my 1950 Knock Out , every person on the back glass is fighting except the cigarette girl, neat game play as well with the boxing ring in center of pf. My fav to play is Seven Seas . Also like Universe and Sunshine.
I am starting to thin the heard so if anyone is interested in, Knock Out, Sunshine,Pin Bowler(Chicago coin) or a rare Bally Roll down"Melody Roll"(ballys first flipper game as roll down) Let me know. PPE was the best place to play a ton of em woodrails, the Thing is cool, Gusher too , the rising pop bumper 40 years before Circus Voltair.
