This post examines the various printings of Canada #464, the 20c Quebec Ferry stamp, from the 1967-1973 Centennial Issue in depth. Included is a lot of detail about the paper types, fluorescence, inks, tagging and gum, that is not available in the Unitrade catalogue. The information is drawn primarily from my knowledge as a dealer and my stock, which contains a large number of reference examples.

This post finishes my examination of the 2d green Queen Victoria first Waterlow Issue of the Niger Coast Protectorate, and begins my examination of the 2.5d carmine lake. For the 2d, I discuss all of the different combinations of perforations that I have found. For the 2.5d, I discuss the shades of ink, paper types, gum, cancellations, plate flaws and re-entries.
