Canada #1061i 8c Multicoloured Parliament Buildings & World Map, 1972 Inter-Parliamentary Union Conference Issue, A VF Canada Post Official FDC DF Cream Envelope, Stamp On Scarcer HF/DF Rolland Paper

A VF canada post official FDC of the 8c multicoloured Parliament Buildings & World Map from the 1972 Inter-Parliamentary Union CoNFerence Issue DF cream envelope, stamp on scarcer HF/DF Rolland paper. The DF envelopes appear to be the standard ones for these issues. 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.

Unitrade does not list this variety, but we estimate the value at $5.
