The illustration reminds me of the cover of a magazine in Ireland some years ago, when the provision of information on abortion was illegal.

I am trying to collect screenshots of internet censorship, preferably from countries that block my blog due to political reaons. Please help: http://andreasmoser.wordpress.com/2011/09/04/censors-dont-like-this-blog/ – Thanks!
