Need information on old doll.

Hi, I do not know of any doll makers with a "Y" mark. It's possible that it is the porcelain body makers mark. I have an
antique/collectibles book around here in my house somewhere that has to be 5 inches thick, that has alot of old dolls listed in it...lol...the problem is I cant find the darn thing..been looking for an hour now.

I will keep looking for it throughout the day and hopefully it will be of some help to you. I have found alot of things in it when I could not find info anywhere else. I will post back if I find it and let you know if it had any info in it.

Thank you! If you can find that book that would be great!

We do know that the mark is on other products we have come across. Everyone refers to the mark as the "Y Corporation", however, we do not know the actual name of the factory. We do know it is based in Japan.

Thank you, if you find that book definitely let us know!
