During World War II, Göring traded 137 paintings for one of Van Meegeren's false Vermeers, and it became one of his most prized possessions. Following the war, Van Meegeren was arrested, as officials believed that he had sold Dutch cultural property to the Nazis. Facing a possible death penalty, Van Meegeren confessed to the less serious charge of forgery. He was convicted on falsification and fraud charges on 12 November 1947, after a brief but highly publicised trial, and was sentenced to one year in prison. He did not serve out his sentence, however; he died 30 December 1947 in the Valerius Clinic in Amsterdam, after two heart attacks. It is estimated that Van Meegeren duped buyers out of the equivalent of more than US$30 million in 1967's money, including the government of the Netherlands.
