THESIS: Christine Garnier, "A Question of Value: The Problem of Natural, National, and Native Origins in the Currency Paintings of John Haberle" MA Thesis, Tufts University, 2015 (Proquest). This thesis interprets John Haberle's trompe l'oeil paintings of money in the context of 19th century American controversies about value. While the full text of this is also available through Proquest's Dissertations and Theses database, I have no descriptive link for the thesis. However, I do have a biographical link for the author, Christine Garnier, who is currently a doctoral student at Harvard.
