For sale: I have an original 2-piece copy of Steinway Duo-Art
blueprint, tubing diagram, drawn by draftsmen employed by John F. Morse
at his Morse Instrument Company on 02/24/56 for Steinway grand Duo-Art
piano serial number 235743.

The drawings are large scale: page one is 30" by 30" (bottom view) and
the second page is 30" by 21" (top view).  I acquired this blueprint in
March 1963 and it is in very nice condition.
