For his letterpress study of masks, Jonny Wan first had the daunting task of structuring centuries of mask history into a four print series. His initial research determined that no matter what period he was looking into, every mask he had found served one of four purposes: ritual, protection, performance, or fashion. Wan chose a mask from each category used in different periods, and printed the series on four different paper stocks using metallic inks. [via FPO]
