I have seen two of these miniature Duo-Art rolls and they both played
the same tune which was Paderewski's Minuet.  One of these rolls is in
the possession of an old man in Lincolnshire, but he won't sell it to me,
despite asking him for 15 years.  The other is with a collector.  I was
given to believe they were given away at exhibitions by sales staff.
