A superb unaddressed official first day cover of the 8c ultramarine Queen Elizabeth II stamp from the 1973-1977 Caricature Issue, with a plate 2 upper right corner block affixed. Printed on vertical wove paper with clear horizontal ribbing. The paper gives a dull fluorescent greyish white reaction under ultraviolet light, with a low density concentration of low fluorescent fibres and a sparse concentration of brownish woodpulp fibres. General OP-2 Ottawa tagging, 4 mm wide, of very weak strength (almost invisible to the naked eye, but with a light azure colour), and glowing a bright yellow under ultraviolet light. Comb perforated 12.0 x 12.5. The envelope stock gives a dull fluorescent brownish reaction under UV light, with a sparse concentration of low fluorescent fibres visible in the paper. Unitrade values a VF-75 cover at $0.85 for the basic NF paper as a single, and does not value any of the paper varieties on FDC, nor does it value plate blocks.
