Vintage Coach Mulberry Bag BLACK authentic

Product Name: Vintage Coach Mulberry Bag BLACK authentic
In good vintage condition overall. It appears very boxy with having an ample 4" depth. Unique shape for a Coach bag. This bag closes at the front with a magnetic closure. The magnetic hardware does not have a typical engraving you see in later bags but one of the Coach Authenticators on the Purse Forum indicated that Coach had known to use these unmarked hardware during the earlier years. This bag also comes with appropriate (for the year manufactured) one-sided hangtag with 'leatherware' stated under the Coach logo. The ball chain however is shorter and chunkier, possibly replaced by previous owner or who knows, maybe original. 8.5" x 8" x 4" There's a missing thread at the strap, about an inch. It's hard to even tell/ see it but letting you know. I want to be transparent with my item. Again, this is a great bag that is in rare style. You don't authentic see this model a lot.
