A well centered and very fine mint NH sealed post office pack of 4 plate 2 blocks of the $2 multicoloured Quebec City definitive from the 1972-1977 Caricature and Landscapes Issue, perf. 11, with the upper left block containing the "Airplane in Sky" variety on position 2. Vertical wove paper, with no ribbing. Smooth creamy PVA gum with a satin sheen. Under ultraviolet light, the paper gives a dull fluorescent greyish white reaction, with a low density concentration of low fluorescent fibres and a sparse concentration of medium fluorescent fibres visible in the paper. The card insert inside the pack is the type 3 Canada Post logo with the small stylized maple leaf, printed in purple, that replaced the earlier multicoloured logo of the same design sometime in 1976. It is printed on a card stock giving a dull fluorescent greyish white reaction under UV light, with a low density concentration of low fluorescent fibres, and a sparse concentration of medium fluorescent fibres, that make it appear MF overall. Unitrade lists a VF-75 NH matched set of the basic plate blocks at $172.50. These packs have become quite scarce now, as most have been opened, and they are very collectible now due to the fact that they can be easily displayed on clear Vario pages. The card inserts can be found in slightly different designs and printed on different types of card stocks. This is a largely unexplored aspect of modern Canadian philately, and I am sure that some of these will turn out to be very scarce, though sadly no data on scarcity currently exists, as far as I know. So I am pricing them with no premium over the price of the plate blocks contained inside them. The blocks offered here grade VF-80 NH, based on the top block in the pack as follows: Margins/centering: 50/70 Paper freshness: 5/5 Colour: 5/5 Impression: 5/5 Absence of visible paper flaws: 5/5 Perforations: 10/10 Note any vertical or horizontal line shown in the scan is the edge of the acetate strip that the stamp was resting inside on the stockcard. Note: the above scan is a stock photo as are all my scans for material after 1952.The item (s) you will receive has (have) been carefully checked to adhere to the above grading standards, so while it (they) may not be exactly the same, it (they) will be of the same quality. Also, I do not provide back scans of NH stamps or blocks after 1952 unless they are required to illustrate some attribute of the paper or gum.
