Former Chinese president Jiang Zemin (???) was there, and then he wasn't -- according to pictures published in Hong Kong yesterday that suggested China's official news agency might have airbrushed him out of a historic photo.
The Standard newspaper ran three versions of a 1992 photo of Chinese leaders, saying at least two images had been doctored, and Jiang had apparently been removed for reasons that remain unclear.
Photo alterations were common in China during the Cultural Revolution of the 1960s and 1970s, when propagandists would delete purged officials from pictures that had shown them next to leaders.
