Hello -- When I turned over the box containing the QRS roll "Bubbling
Spring" (number 80131), I found an interesting label on the bottom,
former librarian that I am.  It reads:

  Notice to Members Circulating Library

  This roll may be exchanged at any time for any other roll of the same
  make.  A fee of five cents per roll is charged for each two weeks or
  less up to three months.  Maximum charge for one year, 30 cents.  Not
  exchangeable if damaged #Only one roll may be taken out for one roll
  returned.  Not less than three rolls exchanged at a time.  All
  exchanges cash.

  Cable Piano Company, Wabash and Jackson, Chicago

Below is a rubber-stamped date: Sep 24, '15.  So it looks like at least
one piano owner borrowed "Bubbling Spring".
