Lot 309 Canada #1040-1041, 1043 32c & 37c Multicoloured Pilots & Christmas Scenes, 1984 Christmas & Royal Air Force Issues, 4 VF Official Canada Post FDC's Franked With UR & LL Inscription Blocks, DF Cream Envelopes

4 VF official Canada Post FDC's of the 32c & 37c multicoloured Pilots & Christmas Scenes from the 1984 Christmas & Royal Air Force Issues franked with UR & LL inscription blocks, DF cream envelopes. 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.

Chung values these at $10.75.
