Chinese Cultural-Revolution Era Clip Art Book
I love Flickr. While looking for some reference material I came across this excellent collection.
The prints look like the could be lino-cuts or wood blocks.
From Oldtasty‘s Flickrset:
This is an outstanding collection of Cultural-Revolution era imagery and propaganda, made available with thanks to Webster University (for use of their scanning station) and Flickr.
Translations will be added over time.
