Okay, I REALLY need some help here...
I am trying to find out the name of a certain type of wall decor that can be seen in the Keaton's living room on Family Ties.
The item is pictured below, and that is the clearest picture I can find.
I am looking for that column of what looks like copper engraved plates within a wood frame housing. I know this type of home decor was popular in the 70's and 80's, and I have tried every possible combination of Google search tags, and also on ebay, but nothing even close to this has come up as a result, and I would REALLY like to know what this item is called, so I can find one to buy for my own house.
If anyone can help me, and identify what this object is, and is called, I'd be very thankful.
