I have a japanese minature musical piano my auntie gave to me when I was young about7 yrs old I am now 33. I have often wonderedd how old this is or any value. I havent looked after it as moved house alot but if it was fixed wuld it be worth anything. There is a sticker on the back saying irene series. I have tried to search this on the internet maybe it was a production called irene series who only made a few of these 1900-1940.?But wanted to sell in the future for someone else to do up or look after. And have pictures of my own miniture piano.
