It was my grandmother's vase. I don't know how old it is, but I remember it being in her house even when I was very little, and I am 45 now. The company name on the bottom is Yankoware, and it was made in Japan. I have searched the Internet for several years now, and every time I do, I just get links to places selling pottery. Not one site had a history of the company, or any information. Thanks in advance if you can help.
I was not asking for appraisal information. I was asking if anyone here knew the possible history. As I stated earlier, I have researched the internet many, many times, only to find sales. If you didn't know, the question could have remained unanswered. So many people here find it necessary to be rude. Sad!
