Imagethief is a big fan of Stefan Landsberger's propaganda poster website, and has often raided it for images. He has also, from time to time, used Maopost, which also has some good material. Now there is a third site available. On his Docs Populi website, archivist Lincoln Cushing has collected scans of more than 500 Cultural Revolution-era posters. The posters are arranged chronologically. At the moment there is no tagging or search function, but it's comprehensive and the scans are larger than many of the other sites, which is useful for some of the more detailed posters. Mr. Cushing tells me that a more full-featured search interface and catalog system is coming, and adds that a little creative Googling can help you search by poster title wording.

Unfortunately there as yet exists no online catalog of truly high resolution images, which is a shame as many of the posters of that era are collections of smaller images or have fine text on them. But at least the range of useful online resources is expanding.

The Docs Populi scans are the result of a project to digitize the posters of Ann Tompkins, an American who sympathized with the revolution and spent time in China in the 1960s. Many of the posters have also been collected in a book, Chinese Posters: Art from the Great Proletarian Cultural Revolution, which might be worth looking at for people who have Landsberger's book or the big poster book by Anchee Min and Duo Duo, or who are simply interested in the topic.

Also highly recommended for anyone in Shanghai is a visit to Yang Peiming's Shanghai Propaganda Poster Art Center, in the basement of President Apartments block B, 868 Huashan Rd. at Changle Rd. RMB20 to get in, but worth every mao, if you'll pardon a pun. 

Thanks to Lincoln Cushing for the heads-up.

Update: Make that two three more sites. See Stefan Landsberger's comment below, and new site under construction, and the University of Westminster site, also referred by Stefan, which has big images too.
