Dogwood in Oriental or Mexican vase.
Rosemarie Manke is a still unidentified (German) printmaker and painter. This surprising and wonderfully Japanese composition was acquired Febr. 2023. Any help discovering who she was is very welcome. You will find all I was able to reveal from the Internet clicking her Artist Name cartouche. It is not much, but hopefully more will come forward with the help of readers and passers-by.
It is possible she emigrated to Monterey, California USA (see biography)
