"Groom's rather predictably provocative thesis is that the forged work is actually the truest one - a case which, in rehearsing a familiar move in deconstructive theory (the deviant is the measure of the normative), is itself a compound of the derivative and the original. Forgery is creative rather than contemptible, rather in the way that a sign, according to Umberto Eco, is anything you can use to lie with. Since there can be no talk of authenticity without the concept of a fake, the phoney is the true ground of great art."
