Ehrenberg's artistic career of more than 50 years covered the conceptual art of the seventies, including mail art and mimeography, a neographical technique of which he was a pioneer. His multifaceted personality rendered a classical classification of his work difficult, so he defined himself as a neologist since the seventies; the term itself is a neologism which underlines the experimental characteristics of his work.^[1] He considered himself an artist, chronicler, professor, politician, diplomatic, editor, actor, organizer, and tireless traveler.
