This is a vintage Chinese Blue and White porcelain bowl marked on the bottom, "Made in China" along with Chinese markings that likely identify the maker. The gorgeous blue & white dish features a series of Asian landscape scenes with mountains, trees, a woman on a bridge, and temples. The blue and white designs cover the interior and exterior of the porcelain bowl. This bowl was gifted to me in 1991 and I suspect it dates to that period making it around 30 years old. It has never been used, kept carefully stowed in a protective box. It is free from breaks or cracks. It is about 8" in diameter and 2.5" in height.
