Over the centuries, a variety of materials have been used to create books and documents. Here, artists Peter and Donna Thomas examine some of the types of paper-like materials that have been used, including amate (Mexican bark paper), birch bark, parchment (treated animal skins), papyrus (plant-based paper originating in Egypt), tapa (bark cloth from the Pacific islands), Tyvek (polyethylene fiber paper) and even a wasp nest. Part historical reference and part artists' book, the accordion style letterpress volume features tipped in samples of the materials on handmade paper.
