I wanted sepia toned paper for the bass. I found an old book for 5 pesos at a street stand. As I worked on the piece I started reading the book. I'd read a page, then cut it up. Eventually I realized it would take too long to finish the piece this way, so I searched for the book on Amazon. Oddly, the book is called ‘Amazona'.
Turns out it is rare and out of print. Oops.
