Canada #591iv (SG#698) 6c Bright Scarlet Pearson 1972-1978 Caricature Issue MF Paper Type 2 Mis-Perf Block VF-75 NH
A very fine NH block of the 6c bright scarlet Lester Pearson stamp from the 1973-1977 Caricature Issue, showing an interesting mis-alignment of the vertical perforations. Printed on vertical wove paper showing no ribbing on either the front or back, and with a burnished smooth texture on the printed surface. The paper gives a dull fluorescent greyish white reaction under ultraviolet light on the face, with a low density concentration of low and medium fluorescent fibres visible. On the back, the paper gives a medium fluorescent bluish reaction, with a low density concentration of low and medium fluorescent fibres visible, as well as very few brownish woodpulp fibres. 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 a very slight horizontal and downward shift of the vertical perforations to the right, mid way down the bottom stamps. This ocurred because this is where one stroke of the perforating comb ends and the other begins. Somehow either the paper or the comb moved slightly so that the perfect continuity of the vertical perforations was not maintained. This is an ideal item to prove that multiple strokes of the perforating comb were required to perforate the panes, rather than a single stroke. Smooth, creamy PVA gum with a satin sheen. Unitrade lists 591iv as MF paper, but I have found 2 different variations of tagging and fluorescence that qualify as MF overall. This is one of those variations. Unitrade values four regular VF-75 NH singles at $4, but a block like this should be worth $10, given the variety. 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.
