Canada #594ii, 594ix 10c Multicoloured Forests, 1972-1979 Landscape Definitive Issue, 2 VFNH Plate 1 & 2 Pairs Type 1 LF3/DF2 Vertically Ribbed Paper & Type 2 On HB10/HB12 Smooth Paper, Perf. 12.5 x 12

2 VFNH plate 1 & 2 pairs of the 10c multicoloured Forests from the 1972-1979 Landscape Definitive Issue type 1 LF3/DF2 vertically ribbed paper & type 2 on HB10/HB12 smooth paper, perf. 12.5 x 12. Includes the following: (1) Type 1, LF3 bluish/DF2 bluish white vertically ribbed paper, nearly solid background, 3 mm OP-2 tag; (2) HB10/HB10 smooth paper, perf. 12.5 x 12 (in prior auctions I have classified this as a HF paper and variant of 594viii, largely because of the fact that Unitrade says that ix is HB on the frint only. I believe now, that this was a typo, due to copying and pasting the description of paper used for the HB $1 Vancouver, which is only HB on front. I have never seen this value HB on the front only, so I believe that this is indeed 594ix.

Unitrade values this at $2.8. The pairs offered here grade 75-80 as follows:

Centering/Margins: 45/70 and 50/70

Paper Freshness: 5/5

Colour: 5/5

Impression: 5/5

Absence of Visible Paper Flaws: 5/5

Perforations: 10/10

The landscape definitives of 1972-1979 are a particularly complex area, with many of the compexities not being listed in Unitrade. Unitrade's description of paper fluorescence is very oversimplified. We have described all the differences we see on these stamps, and in ascribing fluorescence levels we cross -referenced the stamps back to stamps of the Caricature issue that we had sorted into the various fluorescence levels earlier. As a result of this, some of my earlier descriptons have changed slightly, as I have made the determination of fluorescence more accurate. Another aspect that isn't covered in Unitrade, but which clearly differs is the appearance of the photogravure printed background on the 10c, 15c and 50c values. I have described them as "screened background", "semi-solid background", "nearly solid background" and solid background. Screened background, means that all the individual screening dots that make up the coloured area can all be clearly seen as individual dots. Semi-sold background refers to one where some dots are visible, but they are clearly merging into ine another. Nearly sold background means very few, individual dots are visible. Finally on stamps with solid background, the individual screening dots that make up the printing are not individually visible as dots.
