Beschriyvinge ende lof der Stad Haerlem in Holland: in Rym bearbeyd...
This book summerizes the history of the Dutch city of Haarlem, and states that letterpress printing began there. Laurence Koster was introduced as the founder. His portrait and an etching of a purported printing house sometime around the year 1440 were inserted. The honor of the origin of letterpress printing in history was contested between Mainz (Germany) and Haarlem (the Netherlands) for a longtime thereafter. Today, printing materials produced by Koster are believed to have been printed between 1463 and 1480 as a result of a study of the paper and movable types used in production.
