John Railing - Magic of Movable Books: History of Pop-up Books & Paper Engineering - CoM Apr 2021
Movable books began with science and math treatises in the 1500s – had its Golden Age in the late 19th C. – and its renaissance beginning in the 1960s, mainly due to a handful of pioneers in mass-producing hand-assembled books inexpensively. John has amassed a collection of over 6,000 mova
