My father got this cup from my grandfather. he would love to know where it came from. After online research we had many different answers from different experts.

i did try and figure out the marking but didn’t get further then this atm: 製土佳

Some say it’s japanese, some say it is chinese, some say they can’t identify it.
I have been going trough marking databases and found a mix of chinese markings and japanese markings (kanji/meiji)
Contacted the sotheby’s (and other) chinese/japanese ceramics expert in japan and he was a bit baffeled by the stem cup and couldn’t place it in a period or place of origine. but was somewhat enheusiatic about the protrait of a phoenix (as he described it) and the swastica paterns on the inside.

I spend way too much time trying to come up with an answer for my father and would like to ask if anyone can give a good story as to it’s origine?

I have added an imgurl link to the foto’s i have of the cup and sourcer

divinity cup

Regards.
