Canada #1155/1180 1c-80c 1988-1990 Mammals Definitives, A Group of 6 Canada Post Official First Day Covers
6 official Canada Post first day covers, featuring singles of the 43c Lynx and combination covers of the 1-25c, and the other middle values, in groups of three, as they were issued.
The envelopes are all dull fluorescent, except for the one containing the #1172A, 1175 and 1180, which is hibrite. 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 $19.10.
