Canada 1027a, 1039a 32c, 37c, 64c Multicoloured Various Scenes & Locomotives, 1984 Canada Day & Locomotives Issues, 2 VF Canada Post Official FDC's LF and DF Cream Envelopes

2 VF canada post official FDC's of the 32c, 37c, 64c multicoloured Various Scenes & Locomotives from the 1984 Canada Day & Locomotives Issues LF and DF cream envelopes. The DF envelopes appear to be the standard ones for these issues, with LF being an anomaly. 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.
