Canada #587 (SG#694) 2c Green Laurier 1972-1978 Caricature Issue MF/LF Paper Type 3 & 9 Blocks F-70 NH
Three fine NH corner blocks of 4 of the 2c green Sir Wilfred Laurier stamp from the 1973-1977 Caricature Issue, printed on two different varieties of paper. Consists of a plate 1 lower left block, a plate 1 lower right block and a plate 1 upper right. Printed on vertical wove paper showing no ribbing on either the front, or the back. General OP-2 Ottawa tagging, 4 mm wide, of two different intensities as detailed below, and glowing a bright yellow under ultraviolet light. Comb perforated 12.0 x 12.5. Smooth, creamy PVA gum with a satin sheen. 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. The blocks offered here are all the most common type, in which the selvage is fully perforated through on both sides. However, on the lower left block, there were two separate strikes of the perforating comb, as the vertical perforations along the top 2/3rds of the upper stamps are slightly out of alignment with those of the bottom 1/3rd, and the lower stamps. The paper also gives different reactions under UV light as follows:
- On the LL plate 1 block, the paper gives a low fluorescent bluish white reaction on the front, and a low fluorescent bluish white reaction on the back, with a low density concentration of low fluorescent fibres, and very few high fluorescent fibres being visible in the paper. The tagging is of moderate intensity, which means that it is clearly visible to the naked eye, but not dark.
- On the plate 1 UR block, the paper and tagging are the same as the LL block above.
- On the plate 1 LR block, the paper gives a low fluorescent bluish reaction on the face, and a low fluorescent bluish reaction on the back, with a low density concentration of low fluorescent fibres, a very sparse concentration of medium fluorescent fibres, and very few high fluorescent fibres visible in the paper. The tagging is of light strength, which means that it is barely visible to the naked eye.
Unitrade values three F-65 NH blocks at $1.15. 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.
