Canada #593viii (SG#700) 8c Deep Blue Queen Elizabeth II 1972-1978 Caricature Issue Plate 7 UL DF Paper Type 2 F-70 NH

A fine NH plate 7 upper left block of the 8c deep blue Queen Elizabeth II stamp from the 1973-1977 Caricature Issue. Printed on vertical wove paper with no ribbing. The paper gives a dull fluorescent blue grey reaction under ultraviolet light on the front, and a dull fluorescent greyish reaction on the back, with a low density concentration of dull fluorescent fibres visible. General OP-2 Ottawa tagging, 4 mm wide, of moderate strength (clearly visible to the naked eye, but not dark), 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 593viii as DF paper and I have found at least four varieties of DF paper and tagging, which all differ slightly from one another. This is one of those varieties. Unitrade values a F-65 NH block at $2.25. The block offered here grades 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.
