Cellulose-based artefacts and graphic documents on paper, represent a large part of our shared cultural heritage. They are held by institutions such as libraries and archives, which preserve rare and unique historical documents, as well as by museums, art galleries, and private collectors, such as the Calouste Gulbenkian Foundation. An example is the represented «Palmier» by René Bertholo: a kinetic art object composed of several paper trees.
