My name is Alexandre Dias and I am researching the works of Brazilian
composer Ernesto Nazareth.  I've catalogued so far thirty-eight piano
rolls with his music.  Nineteen of the rolls were made in Brazil,
published by Pianauto, and sold at Casa Beethoven (Rio de Janeiro).
None of them are known.

Here is a list of the rolls:

I've decided to dig deeper into this subject, and I'm now interested in
anything related to Brazilian piano rolls.  I'm writing a text about
this topic which will be published soon on the EN150 blog
( http://www.ernestonazareth150anos.com.br/posts ).

Would anyone have any information regarding Brazilian piano rolls, such
as catalog listings or even the rolls themselves?
