In his powerful new picture book memoir The Wall (Frances Foster/FSG, forthcoming in September), Peter Śís quotes from his journals about the darkness following the Prague Spring of 1968:
There is a whole science to learn about dealing with censors. You have to give them something to change. For instance, if you're making a film or a painting, or writing a book or a song, you put in a big church. You can be sure the censors will tell you to take it out, and perhaps they won't notice the smaller, important things. Theater people have the "little white dog" theory. If you let a little white dog parade across the front of the stage, the censors won't notice what is happening in the background.
