A very well centered and very fine mint OG single of the 6c on 5c deep sepia Mercury and globe airmail stamp from the 1932 Ottawa Conference Issue. Vertical wove paper with fine vertical mesh and cream gum with a semi-gloss sheen. Unitrade values a VF-84 OG single at $60. However, examples that are this well centered are elusive and are worth more than the Unitrade price for very fine. The stamp offered here grades VF-82 OG as follows: Margins/centering: 54/70 Paper freshness: 5/5 Colour: 5/5 Impression: 5/5 Absence of visible paper flaws: 5/5 Perforations: 8/10 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.
