Canada #591i,v (SG#698) 6c Scarlet Pearson 1972-1978 Caricature Issue 3 Different DF Papers VF-75 NH

Three very fine NH singles of the 6c scarlet and bright scarlet Lester Pearson stamps from the 1973-1977 Caricature Issue, each printed on a different DF paper. General OP-2 Ottawa tagging, 4 mm wide, of light strength (barely visible to the naked eye), and moderate strength (clearly visible to the naked eye, but not dark), and glowing a bright yellow under ultraviolet light. The paper gives different reactions under UV light and displays different physical characteristics as follows:

• A bright scarlet stamp is on a vertical wove paper with a burnished smooth surface texture. Under UV light, the paper gives a dull fluorescent greyish white reaction on the front and back, with a very sparse concentration of low fluorescent fibres, and a very sparse concentration of brownish woodpulp fibres visible in the paper. Tagging is of moderate strength and the gum is smooth PVA with a satin sheen.
• A bright scarlet stamp is on vertical wove paper with a burnished smooth surface texture. Under UV light the paper gives a dull fluorescent bluish white reaction on the front and back, with a very sparse concentration of medium flurescent fibres and a very sparse concentration of brownish woodpulp fibres visible in the paper. Tagging is of light strength and the gum is creamy PVA with a satin sheen.
• The scarlet stamp is on vertical wove paper that shows clear horizontal ribbing on the printed surface. Under UV light, the paper gives a dull fluorescent greyish reaction on the front, and a low fluorescent bluish white reaction on the back. The tagging is of light strength and the gum is white PVA with an eggshell sheen.
