Thanks to Matthew Caulfield for the information on copyright.  His
comments point out how complex the whole issue is and the need to proceed
with caution.

One small correction to his posting;  Wurlitzer was purchased by Baldwin
(not Steinway).  Wurlitzer pianos are built by Baldwin (also, some are
imported by Baldwin - the Wurlitzer grands).  But, indeed, the old
Wurlitzer firm is gone.

Thanks again for the copyright info.
