This certificate for 100 common shares of North American Pulp and Paper Companies dates from April 1919, just a few months after the Armistice. The North American paper industry was then experiencing a period of strong demand, driven by the rise of the print press and the need for packaging paper for economic reconstruction. W.H. Goadby & Co., the brokerage firm that held this certificate, illustrates the role of financial intermediaries in managing postwar industrial portfolios. The number C8215 indicates a large issue, corresponding to the significant capitalization of these paper conglomerates, which brought together several mills. This document is a valuable witness to the restructuring of the North American paper industry after the world conflict, a pivotal period for the great forestry and wood-processing companies.
