SKU 323014518210

Three very fine NH plate 1 uller left, upper right and lower right blocks of the 4c black William Lyon Mackenzie King stamp from the 1973-1977 Caricature Issue. Printed on vertical wove paper showing no ribbing on either the front, or the back. The paper gives a dull fluorescent blish white reaction under ultraviolet light on the face, with a low density concentration of low fluorescent fibres and a very sparse concentration of medium fluorescent fibres being visible. On the back the paper gives a dull fluorescent bluish reaction, with a low density concentration of low fluorescent fibres, a sparse concentration of medium fluorescent fibres, 1-2 high fluorescent fibres and very few brownish woodpulp fibres visible in the paper. 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, with the selvage fully perforated through in both directions on the lower right block. On the two upper blocks, the selvage is fully perforated through in the horizontal direction, but the vertical perforations stop one full perforation hole short of the edge of the upper selvage tab.  Smooth, creamy PVA gum with a satin sheen. Unitrade lists #589 as being on LF paper, but I have found at least 18 varieties of fluorescence and tagging which closely fits this classification. This is one of those 18 variations. Unitrade values three VF-75 NH plate blocks at $2.25. The blocks 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.
