My piano is a ~115 year old Heintzman. I have had it since I was 8 and I did some beating of the shit out of it for some years. There were the hippy flowers stuck to it through the 70's - and then for years after they were removed you could still see the gluey outline where they had been. I was never shy about bouncing shit off it and whatever else.
My dad put some effort into fixing it up ~20 years ago.
Someone who knows something said it might be worth 2K awhile back.
