Hong Kong’s art community was rocked by the theft that included a two-metre tall scroll containing a 1929 Politburo report written by Mao Zedong valued at hundreds of millions of dollars – but was sold to an amateur collector for just HK$200 (US$25). When police recovered the parchment a month after it was stolen, they discovered it had been cut in half to make it easier to store by the collector, who also did not realise it was genuine. A calligraphy letter and handwritten poem by Mao remain missing, as do dozens of sets of highly prized Chinese stamps, the Post reported. A collector who received some of the goods alerted the police once he realised the items were stolen.
