China 1968 'Mao's Inscription to Japanese Worker Friends' (unissued)
Printed to honor a slogan Mao wrote for Japanese workers, this 8-fen stamp was killed by telegram four days before its release, and the handful that slipped out of a few Hebei post offices became one of the great rarities of the Cultural Revolution.

A slogan for Japanese workers
On the evening of September 18, 1962, Mao Zedong received a Japanese delegation of worker activists in Beijing and, at their request, wrote them an inscription. It reads, in the official English translation: "The Japanese revolution will undoubtedly be victorious, provided the universal truth of Marxism-Leninism is really integrated with the concrete practice of the Japanese revolution." It is signed and dated September 18, 1962.
Beijing's newspapers reported the meeting on their front pages two days later but did not mention the inscription. The Workers' Daily printed Mao's handwriting on November 21, 1965. On September 18, 1968, the sixth anniversary, the major papers printed it again, and the Peking Review carried an English text that week.
That autumn, at the height of the Cultural Revolution, the Ministry of Posts and Telecommunications prepared a commemorative stamp to go on sale on October 1, 1968, National Day, under the issue number Wen 15. The stamp reproduces Mao's calligraphy in black on a red ground, the source of its collector nickname, the "Black Inscription." Archival research published in 2002 dates the stamp's final form to between September 24 and 26, 1968.
Cancelled by telegram
On September 27, 1968, the Communist Party center held a conference on propaganda work. Its theme was how to promote Mao Zedong Thought correctly, and it relayed Mao's instruction that propaganda aimed abroad should not be forced on others. Zhou Enlai, summing up, said that not every kind of product should be printed with Mao's portrait and quotations, though stamps should still be issued and their designs guided properly.
The military control committee running the postal ministry acted the same day. It ruled that stamps would no longer carry Mao's image, quotations or poems; that printed but unissued stamps would be stopped; and that stamps already issued could stay on sale. Urgent telegrams went out to every province, city and autonomous region cancelling two issues set for October 1: this one and "Long Live the Total Victory of the Great Proletarian Cultural Revolution." The stamps were to be returned to Beijing.
A second explanation is widely repeated. Several accounts, including a 2011 BBC report, say the stamp was dropped because Japan objected, fearing the reaction of its own population or accusing China of exporting revolution. A Singapore newspaper's 2019 report describes the Japanese protest as a rumor and gives the propaganda conference as the cause. Both versions are in circulation; the documentary record cited by Chinese sources points to the conference.
The few that got away
Post offices in the Baoding and Shijiazhuang area of Hebei province sold the stamp ahead of the official date, and more copies escaped during the destruction process. Chinese accounts put the number released at fewer than 10. One English-language dealer account places the early sales in Hubei province instead; the Chinese sources consistently say Hebei, and every used copy known carries a Hebei postmark.
Both mint and used copies exist, used ones being more common, and both perforated and imperforate examples are known. At first only one was known in China, displayed in the postal ministry's museum. On September 7, 1985, a used copy postmarked Shijiazhuang, February 9, 1969, turned up at the Shijiazhuang stamp market and was acquired by the Hebei Stamp Company.
The stamp is absent from the People's Republic's own official stamp catalogs and from its official postal history, but Japanese and French catalogs list and illustrate it. International catalogs number it W84.
From 160,000 yuan to a world record
Chinese auction records trace the stamp's rise. A used copy sold in Beijing in 1995 for 160,000 yuan. In 1996 a single brought 300,000 yuan and a pair 600,000 yuan. In November 1997 in Shanghai, a single with a margin made 260,000 yuan and another pair 400,000 yuan. Later singles sold for 144,000 yuan (1998), 176,000 yuan (2002 and 2006) and 88,000 yuan (2007). In January 2010 one sold in Hong Kong for HK$920,000.
The great piece is a corner block of four, believed to be the largest surviving multiple and probably the only block. It came from the Cultural Revolution collection of Ng Siong Tee, which won a gold medal at the 1999 international stamp exhibition in Beijing. Offered at auction in Hong Kong in late February 2011 with an estimate of HK$6 million to HK$8 million, it sold for HK$8,970,000 (US$1,151,630) to a Hong Kong collector, a world record at the time for a Chinese stamp lot at auction.
Single copies remain in demand. In March 2019 a single sold at a spring auction in Hong Kong for HK$552,000, nearly 6 million times its 8-fen face value in the reporter's arithmetic. A mint single with one slightly short perforation has been offered in Hong Kong with an estimate of HK$800,000 to HK$900,000, and a UK dealer has listed one at a guide price of £70,000.
A treasure of the Cultural Revolution
Between 1967 and 1971 the postal service issued 19 sets totaling 80 stamps, distinct in design and heavily political, and they became highly collectible after the Cultural Revolution ended. The rarest are the ones that were withdrawn: the typical pattern was a stamp sold early by a few isolated post offices and then pulled before its official date.
The Black Inscription sits among other withdrawn rarities of the period, such as the unissued 8-fen stamp showing Mao with Lin Biao, prepared to celebrate the victory of the Cultural Revolution, and the map stamp "The Whole Country Is Red," pulled within hours of going on sale on November 25, 1968. Its 2011 sale came as prices for People's Republic stamps were soaring; the BBC reported that many had risen 200 percent or more in two or three years and that supply was not keeping up with demand.

Price record
A realized auction price is what a buyer actually paid on the date shown, including the buyer's premium where the sale reported it. It is the strongest kind of reference price, and it is a record of one sale of one object on one day, not a promise of what the next example will bring.
By reference price, China 1968 'Mao's Inscription to Japanese Worker Friends' (unissued) is number 14 of 100 in the stamps entries of the FLOAT 100. 82 of those 100 rest on a realized sale; the rest carry an asking price or a guide value, and each page says which. Rank within the FLOAT 100 itself (55 here) is editorial: how much an object defines its field, not price alone.
