Canada #1098a, 11029, 1110, 1112a 34c Multicoloured Various Subjects, 1986 Calgary Olympics Issues, 4 VF Official Canada Post FDC's Franked With Inscription Blocks, DF, LF & MF Envelopes, DF & MF Papers

4 VF official Canada Post FDC's of the 34c multicoloured Various Subjects from the 1986 Calgary Olympics Issues. Franked with inscription blocks, DF, LF & MF envelopes, DF & MF papers. The DF envelopes appear to be the standard ones for these issues, with fluorescent envelopes being less common. The fluorescence of the envelopes is an important characteristic that has been ignored by all the catalogues. Why does it matter? Because the envelope is an integral component of the FDC in the same way that a cover would be to a complete booklet, or the cardboard insert would be to a pack of plate blocks. The expectation, and general observation would be that Canada Post would utilize one type of envelope for a particular issue, so that if a different one from the standard type is found, then there is a good chance that it will be scarce, and is therefore, in our opinion collectible. The Peace & Olympics issues are on DF paper and DF envelopes. Canada Day is on DF paper, but a LF envelope. The birds issues are are on MF paper and MF envelopes.
