Knock Knock is a book of concrete poetry knock knock jokes. With a couple of sight gags, a joke with an east London twang, and a low-brow cultural reference thrown in for good measure.
There are two versions; a saddle stitched book with 12 jokes and a perfect bound extended cut with 16 jokes.
The covers are Riso printed in a random mixture of red, black and green on different coloured stock.
