The artist who created the PENvolution installation, Kerstin Schulz, compiled a comprehensive and beautiful catalogue of all the installations to date as well as those still being planned in Hannover’s partner cities: Poznan, Bristol, Rouen, Hiroshima, Blantyre (Malawi) and Hannover. On her return to Bristol, Lynne Evans was able to present a copy of the catalogue to Mayor George Ferguson, who had been involved in early discussions on bringing the installation to Bristol when he visited Hannover in April 2014.
