I don't know how much that original copy is worth, but you should
know that this book has been reissued in 1982, in soft cover, by Bridge
Publishing, Inc., with ISBN 0-88270-532-6.  The pictures have also been
included.

The picture on the cover shows a real street organ but the pictures
on the inside pages are actually small street pianos, also called
automatic dulcimers.  I bought one of these instruments at auction
a couple of years ago.
