Chilean-born artist Eugenio Tellez spent the sixties and seventies traveling the world and collaborating with a number of significant artists. Tellez was thirty-three at the time he made Charte de Vol, by which time he had already held directorial positions at the Atelier 17 etching studio and Ben Shahn Graphic Workshop in Paris and Maine respectively, as well as teaching at the University of Illinois and appearing in numerous international exhibitions. His 1970 appointment as professor of Fine Arts at the University of York brought him to Canada, where he exhibited with Marlborough Godard Gallery in Toronto and from where this print was purchased.
