Canada #1162-1166 37c-39c Queen Elizabeth II, Parliament & Flag, A Group of 7 Canada Post Official First Day Covers
7 official Canada Post first day covers, featuring singles of both 37c and 38c Queen Elizabeth II definitives and Pariament Building Definitives, plus plate blocks of the 37c Parliament and Queen, and 39c flag on low fluorescent Peterborough Paper.
The envelopes are all dull fluorescent, except for the one containing the 37c Parliament plate block, which is low fluorescent. I describe the properties of the envelopes for official FDC's because they are part of the official Canada Post Product, and are supposed to be standardized.
Unitrade cat is $19.60 counting the singles as the basic FDC price and the plate blocks as mint plate blocks.
