I don't know who made this unsigned vase, but think it lovely, with a great silhouette and interesting hand-painted surface design in mossy greens, deep browns, soft blue and gray, which is different on both sides. I think it would feel very Japanese if filled with a couple of small branches of cherry blossoms in the spring, but could swing Scandanavian with some winter berries or a spring tulip or two!
Could be mid-century but maybe more contemporary, I'm really not sure. Excellent condition, without a flaw that I can see. 7 7/8" t x 3 1/8" w x 1 7/8" d.
