Vintage Black Faux Leather Convertible Shoulder Bag Backpack

Great vintage condition. Minor signs of wear shown in pics. I’m not actually sure of material content, the bag feels like it could be a genuine leather but I’m not sure and the straps are definitely not. See close ups. Measurements in pics. Please look at all pics and zoom in for a closer view. Vintage Black Faux Leather Convertible Shoulder Bag Backpack US
