Vintage Gucci black clutch envelope bag

smoke-free home. new but no tag attached. been stored in a closet for 35 years. the top part of the bag is black soft leather. the body part of the bag is a black canvas. no cheese on it. the only place that is labeled g is on the top part of the leather. and only on the front side not on the back side. there's a few little pieces of white felt from the dust bag. it measures 13 and 1/2 in Long by 9" tall by 3 in deep. I think this is called a large envelope bag. no straps. it's brand new without tags. dust bag included. I listed a few of my mother's Gucci bags if you're into vintage Gucci.
