I believe this is a Yixing teapot I believe from the 60s through the 80s. It has leaves on it. It has a maker's mark and is signed.
Owner sold it to me.
This is an older Yixing teapot. If lit is fitting perfectly inside the pot rim it is in many cases a good sign. I know this type of pot very well . They are not rarae but made in republic period in China. I would say around 1940. Again markings are not so interesting but this pot is, because of his age and quality of higher value. Due to the damage value will drop a little of course but in general is this the best pot you showed in MEARTO until now.
