Does anyone have information on a 1950 Francis Bacon Mahogany Baby Grand piano.
Such as what a fair price would be/

I do apologize that no one has addressed your question yet. And, I apologize for not noticing your question sooner. The kind of question that you have, might be better to be placed in the Collectibles topic area of this site. The music section is usually about finding the names to pop songs, but not so much about musical instruments. So, I don't usually go to it as much as some other topic areas.

I have been a piano tuner/technician since 1974. I am also a professional pianist and do appraisals concerning the monetary values of pianos.

What is it's specific horizontal length in inches please, from the front end of the keyboard to the end of the curved part of the rear of it? When was the last time that it was tuned? And, does it hold to standard pitch after it has been tuned?

There are many factors to be considered when trying to find a monetary value of a piano. Knowing the answers to those questions first, will then lead us to other questions and information that will be of value in determining the monetary value of the instrument.

Thanks!
