Early Unauthorized Post Cards

Canada issued its first official post card on June 1, 1871..the U.S. would call theirs postal cards. These cards were for domestic use, authorized to pass throughout the Dominion. Sending these cards to any other country was not authorized. Other postal agencies like the United States, Europe and Newfoundland did not recognize Canadian post cards even though some people tried to add an additional penny stamp and mail them. The United States started issuing postal cards May 1873 and agreed to exchange post cards at a two cent rate. More info to follow if required..stolen from the Canadian Philatelist magazine...
