These rare multiples, mail art pieces, artist's books and audio works by major figures such as Maria Abramovic, Christian Boltanski, Chris Burden and John Cage, are now housed in the National Gallery of Canada. From the collection of over 13,000 items, one hundred have been chosen to illustrate a movement and a time. This singular publication is an essential resource for students, teachers and anyone interested in the origins of contemporary art practice.
