Canada #591iii (SG#698) 6c Bright Scarlet Pearson 1972-1978 Caricature Issue LF Paper Type 15 Plate 1 LL VF-75 NH

A very fine NH plate 1 lower left block of the 6c bright scarlet Lester Pearson stamp from the 1973-1977 Caricature Issue. Printed on vertical wove paper showing no ribbing on either the front or back, and with a burnished smooth texture on the printed surface. The paper gives a dull fluorescent bluish white reaction under ultraviolet light on the face and back, with a low density concentration of low fluorescent fibres, a very sparse concentration of medium fluorescent fibres, and a very sparse concentration of brownish woodpulp 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, with the selvage fully perforated through in both directions. Smooth, creamy PVA gum with a satin sheen. Unitrade lists 591iii as LF paper, but I have found over 15 different variations of tagging and fluorescence that qualify as LF overall. This is one of those variations. Unitrade values a VF-75 NH plate block at $1.25. The block 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.
