Piano, Organ, and Keyboard/Janssen Piano


QUESTION: I have a Janssen Piano that was given to me and it has been refurbished. I am going to sell it, since no one in my family plays and I was wondering what it would be worth.

ANSWER: Hi Linda:

It would be helpful to know the height of the piano from the floor, and the serial number which can be found inside, usually on the steel plate.

A picture wouldn't hurt either.

With that info I can tell the age and give you some idea.

If you're going to include pictures, one of the inside of the piano where the hammers are would be very helpful.

QUESTION: I will get that information, but how do I include a picture?

Hi Linda:

When you resend the info...look on the bottom of the page. I do believe there is a place to insert a picture file or two even just before you send.

There is a section that says, "attach an image". You'll be able to brouse your files and insert a jpeg file.
