An interesting group of 5 upper right corner blocks of the 1c Northern Lights and Dogsled team from the 1967-1973 Centennial issue, printed in the brown and reddish brown shades, all General tagged with 4 mm OP-2 bars, and printed on different types of LF-fl paper, with satin PVA gum, as follows:

  • NF bluish grey ambient fluorescence made brighter by very sparse concentrations of LF and MF fibres, brown, perf. 11.85, 11.9 and 11.85 x 11.9.
  • DF bluish grey ambient fluorescence made brighter by very few LF ad MF fibres, brown, perf not determined.
  • NF bluish grey ambient fluorescence made brighter by very sparse concentrations of LF and MF fibres, reddish brown.

Although Unitrade and Harris both list LF-fl paper, there are several varations which differ according to the overall colour and brightness under UV light, as well as the concentration, if any of LF, MF and HF fibres embedded in the paper, which make it appear brighter than it really is.

The position in the print layout of a block can often be determined by examining the relative widths of the selvedge, as well as by carefully examining the continuity of the tag bars. Upper and lower panes will have the tag bars stop just short of the edge of the selvedge, wheras blocks that show the tagging going all the way through the selvedge will be from the top edge of the bottom panes, or the bottom edge of the top pane. Similarly, the blocks from the centre panes will show a discontinuity in the tagging where one set of tagging bars ends and another begins.

The 1c sheet stamps printed by CBN were printed in a number of different shades, depending on when the printings were made:

  • Plate 1 and 2 printings made between 1967 and 1968 tend to be in shades of violet brown or brown.
  • Plate 1 and 2 printings made between 1968 and 1970 tend to be printed in shades of chocolate and reddish chocolate.
  • Plate 3 and 4 printings made between 1970 and 1971 tend to be printed in shades of deep brown, chocolate or reddish chocolate.
  • Plate 5 printings made between 1971 and 1973 tend to be printed in shades of reddish brown, though chocolate shades are also found.

The collage shows the differences between some of these shades, though they are easier to see in the flesh for some reason.

The gum used on all printings to 1971 is dextrine, but within this category, there are a number of different types, which differ by the way the gum appears, when viewed in light:

  • Early printings have yellowish gum that appears either completely smooth, mildly streaky, or very streaky, and has a semi-gloss sheen.
  • Later printings made toward 1970 have gum that has a distinct satin sheen, and can occasionally appear grainy.
  • Plate 3 and 4 printings made between 1970 and 1971 often have a gum that appears mottled and "sponged on". This is a very distinct look that is not seen on the earlier plate 1 and 2 printings. However, the normal smooth and streaky versions of the dextrine gum is also found on these printings as well.

The PVA gum used on the plate 5 printings, shows very little variation, but a subtle difference can be found in the sheen and thickness of the gum, with the earlier printings having a thicker gum with a satin sheen, compared to a slightly thinner gum that has an eggshell sheen.

Unitrade values these blocks at $7.50. The blocks are VF, grading between 75 and 84,

The perfs are unlisted and unidentified in these lots, but a combination of any of the following measurements exist for each side: 12, 11.9, 11.95 and 11.85.
