Felipe Ehrenberg. Codex Aeroscriptus Ehrenbergensis: A Visual Score of Iconotropisms. (Atlanta: Nexus Press, 1990). Limited edition: 500 copies.

I have been making and using stencils for nearly five and twenty years. They are much more than a mere device to help me create retinal art, be this drawn, painted or printed… For this book (which, like many other codices, should ideally be read like a detective novel) I have laid out my best beloved stencils. With these I seek to offer viewers various clues that you may unravel the wondrous and dramatic events surrounding the life of this artist, another witness to the end of a century. This work is also intended to serve as a musical score, perhaps to be composed by someone wishing to recreate the background music of our daily histories.
