I just found a vintage miller high life beer sign in my wife's grandparents house. It seems like it is made of iron as it is very heavy. I couldn't really read the numbers on the manufacturers plate except the series which was 1967. So I'm guess it was made around 1967. So I was wondering what this sign might be worth and also the best way to clean it up a bit. This is my first post and plan on coming back often because I just ordered my first home brewer kit. My neighbor has been brewery for 6 months now and he got me hooked.
