Additional information concerning instruction rolls issued by the
Gulbransen Piano Co.  I am aware of (3) editions of these rolls.  The
first edition is a (6) roll set, the second edition is a (4) roll set,
and the third edition is also a (4) roll set with revisions, and is
copyrighted  1923.  All  (3) editions were produced by the Q.R.S. Co.
Other later editions of these rolls may have been issued.
