Chinese Xuande Mark Vintage Ming Style Calligraphy Celadon Small Bowl

A small porcelain celadon bowl with blue Chinese calligraphy letters. I tend to think this is a vintage piece done in the Ming dynasty style, but just my uneducated guess. 

size 5.25" diameter at rim... 2" tall... weight 8.8 oz.

Very Good condition with no chips or issues.
