The Centennial Definitives of Canada, 1967 to 1973 exhibit is divided into two parts: the basic adhesive stamps and supplementary categories, including the varieties, booklet pane covers, cello-paq envelopes, tagged stamps, regular issue postal and special-order stationery, followed by extensive coverage of Centennial postal history. One feature of the exhibit is the imaginative way the author has chosen to display some of the material.

Doug Irwin has been collecting and exhibiting all aspects of the Centennial definitives since the 1970s. He has written extensively on the issue in BNA Topics, The Canadian Philatelist and Canadian Stamp News. In 1981, he formed the BNAPS Centennial Definitives Study Group and was the editor of its newsletter for many years.

Doug was the major contributor to the revised (second) edition of Canada The 1967-73 Definitive Issue as well as contributing to Centennial Definitive Series 1967 – 1973 and the Centennial section of Canadian Stamp Handbooks.

Doug has exhibited the Centennial definitives at national level shows in both Canada and the United States, as well as in the Court of Honour at the revitalized Stampex (put on by the Greater Toronto Area Philatelic Alliance), in CAPEX 87 and as a single frame of the $1 stamp in CAPEX 22. The exhibit shown in this book was awarded a large gold medal and the BNAPS “Best BNA Exhibit” at CANPEX in 2019.
