The Graceful Ghost Rag by William Bolcom was issued on a piano roll in 1986
by Artcraft Music Rolls of Wiscasset, Maine.  These rolls are the creations
of L. Douglas Henderson who arranges and hand-punches the master on a
Leabarjan perforator.  This particular one is for the Duo-Art piano.  Since
he makes only small production runs of each title, there may not be any left.
But, of course, you should contact him directly to find out about
availability.
