Vintage 1940's glazed pottery, birds on a limb vase

Vintage pair of birds, figurine is made of glazed pottery from the 40's. Measures about 5" tall. I think this one is also a violet vase, as the stump is open and the bottom is solid to hold water. Marked M K Japan in black ink stamp on the bottom. Perfect condition, no chips cracks or crazing. Email for photo of back side. Other side shows more colorful blue's and brown's, Very pretty!
