This presentation by Philatelic Specialists Society of Canada is based on Kem Pugh’s book dealing with the forgeries by Giovanni Patroni. There is much to be done in identifying all of Patroni’s forgeries. Patroni’s British North American (BNA) forgeries are not well identified in the literature, and they are often attributed to other forgers such as Zechmeyer and Spiro. Gerhard Lang-Valchs was instrumental in identifying several of them in correspondence with Ken.
