Quentin Blake is a master of the kind of illustration that looks easy but is damn hard to get right. I love his work. Love this poster. Love the content - readers gotta' have rights - right? Lots of love going on here. Daniel Pennac's book, The Rights of Readers was first published in 1992 then retranslated from the French in 2008 with a forward and illustrations by Blake. Thanks to Book Browse for the info.
