Thanks for the year of opening. The invitation is in very good condition considering it's 53 years old -- the cover is a bit soiled but the inside is very clean and there are NO tears in the paper and the corners are good. Does anyone know the approximate value? I don't recall one being offered on eBay and only seen those such as Caesars Palace being mentioned here.

Thanks for any further info.

Best regards,
