Canada 1972-1977 Landscape Definitives Polar Bears

Hi to all

Pictured is Unitrade 597, one is a type I and one is a type 11, but the one on the extreme left has big blue blotch between the bears and the shadow is different also. I checked it under the microscope and it is definately a colour blotch of dark blue.
So is it a type or 11 or none of them.
The rate I am finding Canadian Varieties in the accumulation, I could start a specialist collection just on them.
