Canada #593 (SG#700)i, iv 8c Ultramarine Queen Elizabeth II 1972-1978 Caricature Issue DF & LF Paper Types 3 & 4 VF-80 NH

Two well centered and very fine NH singles of the 8c ultramarine Queen Elizabeth II stamp from the 1973-1977 Caricature Issue, each printed on a different paper. General OP-2 Ottawa tagging, 4 mm wide, of very weak strength (almost invisible to the naked eye) and glowing a bright yellow under ultraviolet light. The paper gives different reactions under UV light, and exhibits different physical characteristics as follows:

• One stamp is on smooth, vertical wove paper, that gives a dull fluorescent greyish reaction under UV light on the face, and a dull fluorescent grey blue reaction on the back.
• One stamp is on horizontal ribbed paper, and gives a dull fluorescent blue grey reaction on the front and back, with a low density concentration of low fluorescent fibres, and a sparse concentration of brownish woodpulp fibres, visible in the paper. The tagging is a light azure colour in normal light.

Comb perforated 12.0 x 12.5. Unitrade values two VF-75 NH singles at $0.65.
