Canada three volume collection / exhibit in production of the Parliament and Peace tower issues of 1977 -1982 Peace Tower series, 1982-1989 Artifact and Parliament series and 1985 Parliament and Cameo. A great deal written up and already mounted on exhibit pages including varieties, tagging, perfins, cover usages and most especially extensive examination of booklets and varieties (partial missing values etc.). An exciting and under studied area of Canadian philately waiting for a specialist to "own" these issues. Be the resident expert. See longleyauctions.com for more scans.
