This is an antique one-piece hand-carved glass display cabinet/breakfront.
It's either from the 1930s or the 1940s. I am not an expert on this.
It is a solid one-piece of furniture measuring 69 ½” high by 46” wide by 20” deep at the bottom and 18 ½” deep at the top. It has three glass shelves. It does not have a key. The bottom has a door in the center.
I think it is a walnut, and the only marking is F: B 1661 or F:B: IGGI carved on the inside of the top (see photographs). There are scuffs on the left side. It needs restoration.
It is located in a basement of a building in Glencoe. There is an elevator. You will need to provide personnel to load it in your truck.
