1965 Gottlieb Cow Poke backglass. Good condition, no holes, some minor scratches/marks, what looks to be a burn mark between the 5 and 6 at the bottom, I've had it for years and I only noticed this when I photographed it.
Some fading to the 1,2,3,4 and 5 numbers at the bottom but overall the backglass is in fairly good condition.
