20th C. Chinese Yixing Clay Teapot Pottery Calligraphy Script Vintage Decorated
This vintage Chinese Yxing clay teapot is decorated with script and woodsy like raised decorations including a bat on the cover and it is signed on the bottom.
I believe it was made in the 20th century but I am no expert so hopefully the mark and pictures will help.
Condition: It looks like there is some roughness in spots on the end of the spout with a small chip. The pot is beautiful.
Measurements: 7 1/2" long from handle to spout x 4 1/2" wide x 4" tall.  Weight before packing: 13.4 oz.
Thanks for looking.
