Canada #592 (SG#699) 7c Deep Brown St. Laurent 1972-1978 Caricature Issue DF Paper Type 6 Plate 1 LR/UR F-70 NH
Two fine NH plate 1 upper and lower right blocks of the 7c deep brown Louis St. Laurent 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 greyish reaction under ultraviolet light on the face and a dull fluorescent greyish violet reaction on the back. General OP-2 Ottawa tagging, 4 mm wide, of very weak strength (almost invisible 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 the vertical direction, and a single extension hole in the right margin. Smooth, white PVA gum with a satin sheen. Unitrade lists 592 as DF paper, but I have found at least 9 different variations of tagging and fluorescence that qualify as DF overall. This is one of those variations. Unitrade values two F-65 NH plate blocks of the basic DF paper at $1.25. The blocks offered here grade 70 as follows: Margins/centering: 40/70 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.
