My Thrift Store Find

Hello,
Please help me to know what time period this piece was made.
I bought this at a thrift store. It's in excellent condition. I could not see any indication of who made this piece, unless it is on the back or the bottom. It is 80 in. tall, approx. 6 ft. 8 in.; It is 55 in wide at the bottom, and it is over 1 ft. deep. The glass has a wire mesh. This piece is one solid piece -- The top part does not come apart from the bottom. I'm guessing this may be somewhere from the 1970's. I have looked and looked all over the internet, and I have found some similar pieces, but none that look exactly like this one. And it includes lighting. Please help.
