“One can imagine a near-future museum with every important artwork in the world – the entire contents of E H Gombrich’s 1950 classic The Story of Art – made manifest in a single super-didactic replica collection. This is not necessarily a bad thing, as long as no one feels fooled. A copy is just a copy, entirely legal and often useful (not least for scholarship and education), and becomes a forgery only if the work is used to defraud.”
