Dickinson, Gary (2011). A.C. Roessler’s Canadiana.

“A.C. Roessler’s Canadiana” by Gary Dickinson, is the result of many years of studying and collecting Canadian covers bearing cachets, not only First Day Covers but also those printed for commercial First Flights and other events such as Newfoundland joining Confederation in 1949. While sometimes spoken of in less than positive terms because he was so prolific, Gary recognized that Roessler had made a significant contribution to Canadian philately and decided to record his work in one volume. Gary is the author of many articles on cacheted covers in BNA Topics and is also the Editor of the newsletter of the BNAPS First Day Cover Study Group.
