Canada #588 (SG#695) 3c Maroon Borden 1972-1978 Caricature Issue LF Paper Types 3 & 6 VF-80 NH

Two well centered and very fine NH singles of the 3c maroon Robert Borden stamp from the 1973-1977 Caricature Issue, each printed on different papers. Printed on vertical wove paper showing no ribbing on either the front, or the back. General OP-2 Ottawa tagging, 4 mm wide, of both moderate strength (clearly visible to the naked eye, but not dark) and 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. The paper gives different reactions under UV light as follows:

• a dull fluorescent greyish white on the face and back with a low density concentration of low fluorescent fibres, a sparse concentration of medium fluorescent fibres, and very few high fluorescent fibres visible on both sides. The tagging is of moderate strength.
• a low fluorescent bluish reaction on the front and back, with a sparse concentration of low fluorescent fibres, very few medium fluorescent fibres and a very sparse concentration of brownish woodpulp fibres, visible in the paper. The tagging is of light strength.

Unitrade lists #588 as LF paper. I have found at least 16 varieties of fluorescence and tagging that closely fit the description of LF overall. These two stamps are two varietes of this paper type. Unitrade values two VF-75 NH singles at $0.50. The stamps offered here grade 80 as follows: Margins/centering: 50/70 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.
