From the amazing book Brasil, 1920-1950: da antropofagia a Brasília : MAB-FAAP Museu de Arte Brasileira, 30 novembro 2002 a 02 março 2003, by Jorge Schwartz, this series of photos of Villa-Lobos by Manossolfa, taken in the 1930s. The original prints are in the Museu Villa-Lobos.

This book may be hard to find - you'll need to scour used bookstores and schmooz with interlibrary loan staff at your library. In the meantime, go to Google Books for a view.
