Two very fine mint NH singles of the 8c dark blue swimming stamp from the 1974 Keep Fit Sports Issue, with moderate General Ottawa 4 mm OP-2 tagging, each printed in a different shade of the dark blue. Line perf. 11.85 x 11.85. Horizontal wove paper with no ribbing or vertical mesh. Smooth creamy PVA gum with an eggshell sheen. Under ultraviolet light, the paper appears dull fluorescent bluish white, with a sparse concentration of low fluorescent fibres and a sparse concentration of brownish woodpulp fibres visible in the paper. The tagging on the stamps is of moderate strength, which means that it is light yellow and clearly visible to the naked eye (see the second scan for examples of all three tagging intensities). Unitrade lists this stamp as being on DF paper, but this is a gross over-simplification, as the above description shows. There are in fact, at least five different types of the DF paper, and three different tagging strengths (light, moderate and dark), for a total of at least fifteen varieties. The scarcity of these varieties varies widely, with this being by far, the most common, based on my examination of over 800 plate blocks and se-tenant blocks. Unitrade lists two VF-75 NH singles at $1. The stamps offered here grades VF-75 NH, as follows:
Paper freshness: 5/5
Absence of visible paper flaws: 5/5
Note any vertical or horizontal line shown in the scan is the edge of the acetate strip that the stamp was resting inside on the stockcard.
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.
