Hi Margaret, Judging from painting style and decoration it could have been made in the 20s, but no earlier. The mark is in the style of a company logo, which would have been started about that time.
Condition is generally good, almost too good, with not wear to the gilt. That would warrant a closeup inspection of bottom, foot rim and interior, to verify possible age. Either it was not used at all (and well cared for), or it is newer, in my view. Overall it looks like Qianjiang style porcelain.
