Vintage T.N.B.C. interchangeable messenger bag

Purchased in the early 90's; i believe this was made BEFORE Disney took over The Nightmare Before Christmas. The front flap is reversible, w/ Jack sewn on as a patch on one side, and just his iconic grin in white velvet (?) on the other (last pic shows how it unzips to display either side). Awesome attention to detail, including Jack on the coffin-shaped zipper - multiple internal and external pockets, with pen holders and even a detachable old school phone holder. All zippers, snaps, adjustable shoulder strap, etc in excellent working order. Only visible wear is in the bottom corners (pls see pics).
