Canada #588xx (SG#695) 3c Maroon Borden 1972-1978 Caricature Issue Precancel LF Paper Type 6 UR VF-75 NH

A very fine NH blank upper right warning block of the 3c maroon precancelled Robert Borden 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 bluish grey reaction under ultraviolet light on the face. The back gives a low fluorescent bluish reaction, with sparse concentrations of low and medium fluorescent fibres, a very sparse concentration of 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. Smooth, creamy PVA gum with a satin sheen. Unitrade does not price corner blocks, but values four VF-75 NH singles at $1. The block 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.
