"The book, written entirely in English, presents the banknote creations of the Slovak artist Matej Gábris, who sees himself as a "conceptual music maker". Impressive is the artistic ingenuity, from which ultimately his fantasy notes emerge. After an introduction that deals with fantasy banknotes in general, the artistic design of banknotes and security printing, a kind of catalog begins in which all the banknotes projects of the artist are presented. Very clever from the publisher, that the book also as an encore added a fancy note, the desire to do more. It is a 2019 "Banco di Firenze" 500 lire note, labeled as "no value pattern"."
