Canada #791T6 30c Deep Magenta And Black Queen Elizabeth II, 1977-1982 Floral & Environment Issue, A Very Fine Used Single on Piece, Showing a G2cR Tagging Error

A very fine used single on piece of the 30c deep magenta, grey and black Queen Elizabeth II stamp from the 1977-1982 Floral & Environmental issue, showing a G2cR tagging error in which there is only a single tagging bar along the right side. Printed on paper that reads as NF on the front and appears to be fluorescent on the back (the fluorescence comes through) and with dotted background.

The Queen Elizabeth stamps of this series can be found printed with background colours that appear more or less even and solid, with colours that appear mottled, and finally with backgrounds where the screening dots are very clearly visible (the dotted background.) Again this is not listed in Unitrade, but in my view it is a very collectible difference.
