I have owned this sign for nearly 30 years. A new friend who collects old signs was at the house recently and told me this sign was quite unique, that he'd never seen one like this before and thought it might be quite valuable, even in its condition. I have no interest in selling it, but love the distressed grungy look. Just wanting to get some more info on it. It appears to have knockouts where perhaps neon lighting used to attach? Can anyone guide me on this? (Hopefully the image attached) Thank you.
