Collectors are willing to pay exorbitant prices for art when they think it’s rare. But photography has this problem of reproducibility, which was got around by the concept of the “vintage” print. “How problematic the theory has become is further illustrated by two recent scandals involving counterfeit vintage prints by Man Ray and Lewis Hine, and by the Walker Evans retrospective at the Metropolitan Museum, carefully stocked with old prints when newer and, in some cases, finer ones were readily available.” – New York Times
