MCM Brutalist Crow Mug & Goblet Set Pottery Salt Works Monroe?? Black Bird Beautiful vintage mug and coordinating goblets with wood stems. I’m not sure the maker on these and I don’t recognize the stamp. Awesome style and will make a great addition to a unique collection. No chips and good vintage condition. Smoke free home.
