Two very fine NH plate 1 upper left blocks of the 2c green Sir Wilfred Laurier stamp from the 1973-1977 Caricature Issue, showing two different comb perforation configurations. Printed on vertical wove paper showing no ribbing on either the front, or the back. The paper gives a low fluorescent bluish reaction under ultraviolet light on the face, and a low fluorescent bluish white reaction on the back, with a low density concentration of low fluorescent 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. Smooth, creamy PVA gum with a satin sheen. Unitrade lists #587 as MF/LF paper, but I have found at least 11 varieties of fluorescence and tagging which closely fits this classification. This is one of those 11 variations. These were the first comb perforated stamps printed by the CBN, and there were different configurations of the perforating combs that can be distinguished by looking at the selvage. Here we can see two types:

  1. On one block, the vertical perforating holes stop, one full hole short of the top edge of the selvage, while the left selvage is completely perforated through.
  2. On another block, both the upper and left selvage are perforated all the way through.

Unitrade does not differentiate between these two different types of perforation, and values two VF-75 NH blocks at $1.50. The blocks offered here grade 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.
