I have been searching for a Gottlieb Circus backglass for 5 years now for my HUO Circus (minus a bg, long story).
I finally found one but it was well used. Decent but used. The only time I ever saw a nice Circus backglass come up was when someone was selling a combo with an NOS pf and it went for crazy money.
Long story short, I too would be in for repro! How can we make this happen? That artwork is awesome on this game!
