Canada #591xxiii (SG#698) 6c Scarlet Pearson 1972-1978 Caricature Issue Precancel Vertical Hairline VF-75 NH

A very fine NH pair of the 6c precancelled bright scarlet Lester Pearson stamp from the 1973-1977 Caricature Issue on the HF paper, showing a fine vertical hairline running through the design. Printed on vertical wove paper showing no ribbing on either the front or back, and a smooth, burnished texture on the printed surface. The paper gives a medium fluorescent bluish white reaction under ultraviolet light on the face and back, with low density concentrations of low and medium fluorescent fibres visible in the paper. General OP-2 Ottawa tagging, 4 mm wide, of light strength (barely visible to the naked eye), and glowing a bright yellow under ultraviolet light. Comb perforated 12.0 x 12.5. Smooth, cream PVA gum with a satin sheen. Unitrade lists 591xx as MF paper and 591xxiii as HF paper and does not list LF paper. This paper is bright enough in comparison to the "MF" examples to be considered HF. In fact I found 8 varieties of tagging and fluorescence that can be considered as the HF paper. This is one of those 8. The hairline on the stamp runs just to the left of the "O" of "Postage". Unitrade values a VF-75 NH single without the variety at $2. The stamp offered here grades 75 as follows: Margins/centering: 45/70 Paper freshness: 5/5 Colour: 5/5 Impression: 5/5 Absence of visible paper flaws: 5/5 Perforations: 10/10 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.
