Book XIII has been used as merchandise in an art event about the Artist's book (WKB18, Groningen, NL October 2018). The paper bag was a free gift for anyone who purchased an Artist's book during the event.
On the inside of the paper bag - hidden under the folding edges near the handles - true size images of Paperfish (Ctenolepisma longicaudata) can be found. These insects often hide in books, old newspapers or paper archives. They feed on paper and can cause great damage.
Book XIII (as edition) is available at: ARTisBOOKshop
