Can anyone help me figure out the manufacturer and/or value of this furniture? I think it's from the mid 60s to early 70s. I included a picture of the only markings, which are on the underside of the table. It belongs to my in-laws who are downsizing to a condo, and we're trying to figure out if it's worth keeping in the family or if we should sell it. They bought it from an individual so they don't know where it originally came from or what it was worth. Thanks in advance for any help!
