David Sax, the author of three books—on delis, on the revival of analog culture, and on the right way to look at entrepreneurship—offers insights into the joy people feel in letterpress printing and the way in which cottage businesses dominated the world, and still do. Printing and letterpress aficionados will particularly like his 2016 title, The Revenge of Analog. His new book is The Soul of an Entrepreneur (April 2020).
