I have been renovating my basement to turn it into a play room for my 3 year old and my daughter who is due Dec 1st. The house was built in 1960, and we bought it from an elderly couple who probably had not had kids there in 30-40 years or so. This was tucked behind an old baseboard. I almost threw it away thinking it was an electrical box punch out (I had some electrical work done recently), but noticed it had writing on it. I cleaned it up and it turns out it has some pretty toning on it as well! OK, might not be worth a lot, but it was still fun to find
