I bought my first Duo-art reproducer in 1974 and at one point had
over 3000 Duo-art rolls.  I saw a roll today that I have not seen
before.  It is Duo-Art 9569, Visuola Home series, Chopin's Prelude,
Op. 28 No. 20, played by Sophie Pratt Bostelmann of the Aeolian Hall
School for Music Research.  Does anyone have any information on the
Visuola series?
