Vintage Dooney & Bourke emerald green crossbody bag

Vintage 80’s/90’s emerald green Dooney & Bourke crossbody bag. There is wear (see photos) but still has lots of life left. The crossbody strap does not have any holes, only a buckle that can be adjusted so I don’t know if this is a replacement strap (it has D&B hardware), and there’s one pen mark on the strap. Beautiful color and classic style!
