Canada #587iii (SG#694) 2c Green Laurier 1972-1978 Caricature Issue DF Paper Type 3 UL Blank Block VF-75 NH

A well centered and very fine NH blank field stock upper left block of the 2c green Sir Wilfred Laurier stamp from the 1973-1977 Caricature Issue, showing an oval flaw inside the upper middle tagging bar. Printed on vertical wove paper showing no ribbing on either the front, or the back. The paper gives a dull fluorescent bluish white reaction under ultraviolet light on the face, and a dull fluorescent greyish white reaction on the back, with a sparse concentration of low 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, creamy PVA gum with a satin sheen. Unitrade lists #587iii as DF paper, but I have found at least 19 varieties of fluorescence and tagging which closely fits this classification. This is one of those 19 variations. Unitrade values a VF-75 NH plate block, without the tagging flaw at $1.50. The field stock blocks on these low value definitives are actually scarcer than the plate blocks.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.
