Hello
Is this a rerpo marquee or not 
It has a midway logo but not the yellow
I compared it to my original...and mine says "MIDWAY A Bally Company". Where as yours says just Midway. Also, the MIDWAY on mine is yellow. The Copyright on mine says 1981.
So if the copyright on yours says 1981, then it must be a repro. IMO
Or perhaps it's a rare early version, but I've never seen one like that.
