I doubt the censors were sent in because of the deleterious effects on U.S. politics:
President Obama spent the second day of his state visit to China in the capital Monday, and the government adopted a two-track policy toward Obama memorabilia for sale here: Obama dressed as Superman was in, and Obama dressed as a Red Guard was out.
Liu Mingjie learned the latter lesson. He is the designer and entrepreneur behind the popular "Oba Mao" image, which takes a silk-screen likeness of Obama and dresses him in a green jacket and cap to resemble the late Communist leader Mao Zedong.
Since September, Liu's shop had been doing a brisk business selling the hugely popular Oba Mao T-shirts, purses and magnets. Oba Mao became one of the hottest-selling items in town, particularly among urban young people and online "netizens." Oba Mao melded two iconic images -- even if no one could explain precisely what it meant.
But suddenly last week, Liu had no more supplies, and no explanation why.
Liu nervously did not want to answer a reporter's questions. He also removed most of the Oba Mao articles and photos from his blog.
But neighbors in nearby shops reported that they were all visited last week by uniformed officers from Beijing's Industry and Commerce Administration and were told they were not allowed to sell anything with Obama's image, and particularly not Oba Mao items.
But another Beijing shop, called Grifted, selling politically themed merchandise, seems to have been immune from last week's crackdown. The store was selling an Obama action doll dressed as Superman, right next to Mao in uniform.
P.P. Xiong, the creator of the Obama-Superman toy, said he came up with the design because "I like Obama a lot. And I made such a design after the inauguration. I think American people have high expectations for Obama, and I hope he will come to help the U.S. just like Superman."
For the record, at least two officials of the Industry and Commerce Administration denied the shopkeepers' claims that they had been asked to stop selling Obama merchandise.
"Now with the ever-deepening opening of Chinese society, things like those are more acceptable to the government," said Yang Yue, a media officer with the administration.
For example, the designers of a T-shirt depicting Obama as a horned vampire have managed to fly under the radar because their product is available only online.
The purveyors of the vampire shirt say their goal was to emphasize how the United States is sucking the life out of the global economy. But in addition, they offer an alternative: a T-shirt with Obama as a magician in a top hat, just in case his economic prescriptions turn out to work magic. There was no immediate word on which version was selling better.
