German Black Leather Folio Zipp

Rather nice quality vintage German leather folio or portfolio. The only markings are on the zipper (Zipp). Made from a finer grade of leather with a nice artificial silk lining. It has one outer zip pocket, one small inner pocket and a large main pocket with a divider. I am not entirely sure of its age but it roughly from the 40's-70's and more than likely is from around the 60's. The style and materials are equally appropriate and are often found on much older office items. It is in good condition with some general age and some scuffs on the bottom corners. There is no key.
