I recently came across an interesting Jose Iturbi concert program.
At the bottom of the front page it reads:

  Victor Records
  Aeolian Duo-Art Recordings

There is no date on it, but it must be after 1937, as the reference to
George Gershwin lists him being as deceased.  I found it interesting to
find a Duo-Art reference so late.  I know Iturbi made rolls, but for
what reproducing system?

Just an oddity I thought I'd pass on.
