Canada #1107ai 34c 1986 Explorers Issue, A VF Official Canada Post FDC Franked With LR Inscription Block Showing the Constant Pink Print Flaw At Left of LL Stamp, DF Cream Envelope, DF2/DF2 Harrison Paper

1 VF official Canada Post FDC of the 34c multicoloured Various Exploration Scenes from the 1986 Explorer's issue. Franked with LR inscription block showing the constant pink print flaw at left of ll stamp, DF cream envelope, DF2/DF2 Harrison paper. 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.

Chung values this at $7.5.
