Lot #61 Canada McCann #BK69j 1c Purple Brown, 6c Black, And 8c Slate, 1967-1973 Centennial Issue, A VFNH 25c Booklet, Type 1 Free Dispenser Cover, Coarse Font, Black Sealing Strip, HF-fl Smooth Paper, Setting B, Showing Thick Line to Left of 8

A VFNH complete 25c booklet containing a pane of 6 of the 1c purple brown Northern Lights and Dogsled Team, 6c black Trasportation and 8c slate Parliamentary Library stamps from the 1967-1973 Centennial issue, with type 1 "Free Dispenser" cover that has a black sealing strip. Printed on HF-fl bluish white smooth paper that is inherently MF and contains a sprase concentration of HF and HB fibres that makes it appear HF-fl. Coarse cover font and setting B, as described in Harris. This example shows a most striking and unusual plate flaw in the form of a thick horizontal line from the left of the "8" on 3/1 to the left frameline.

Although Unitrade, McCann and Harris list HF paper, there are several variations of this paper. All give a bluish to bluish white glow under UV, but the papers contain different concentratons of LF and MF fibres, which make the paper appear brighter, as well as different concentrations of brownish woodpulp fibres, which counterct the fluorescence, making the paper appear duller. Some of the papers are smooth, while others display light vertical ribbing on the printed surface. The different settings are discussed in Harris, as described by Leopold Beaudet and there are three: Setting A has the lower left corner of the 1c stamp at 2/2 located well to the right of the upper left corner of the bottom 8c at 3/2. Setting B is similar, but this time the corner of the 1c is just barely to the right of the 8c, and on setting C the corner of the 1c is to the left of the corner of the 8c. The OP-4 tagging on these booklets exists with 3 bar spacings: 20 mm between both sets of bars, 19mm between the bars on the left and 20 mm on the right, and 20 mm on the left bars and 19 mm on the right.

The 1c booklet stamps printed by BABN were printed in at least two shades:

• The 1c stamps are found in purple brown and violet brown shades.

The gum used on these booklets is a white PVA with a satin sheen.

This line variety is not listed in either Unitrade, Harris or McCann, but my estimate of a reasonable value is $50, given how striking it is. The booklet offered here is VF and grades 75.
