Traquair, Robert (2002). Canada Perfins Used on Cover.

Robert (Bob) Traquair was active in the philatelic community for over fifty years, starting as a serious collector in the 1950s as an active member of the Calgary Philatelic Society. Bob was a collector of many areas of Canadian philately: constant plate flaws and varieties, postal stationery, mint and used stamps, booklets, perfins on stamps and perfins on cover. His perfins on cover gave Bob his greatest enjoyment in philately – these “stamps with holes” were often considered as damaged and not worth collecting. Many collectors have formed collections of perfinned stamps, but it is quite remarkable to view the Robert Traquair collection of Canadian Perfins on Cover.
