Ditto!
In looking through the 1972 set, two things struck me.
1. The 8c Krieghof stamp shown displays the "broken doorframe" variety.
2. The 10c medium value definitive - "Forests of Central Canada". I have a plate block of this (I'm away from home so don't have access to plate number or scans) which does not show any fluorescence whatsoever. I originally though (hoped?) this was the untagged variety but it was pointed out that, if held in just a certain way to the light, you can see a difference in the surface lustre where the tagging should have been. Now I know that one variety of the stamp used the tagging type that is extremely fugitive. This PB has, however, been in the same glassine envelope since I bought it from
Canada Post. The glassine envelope shows no sign of the missing flourecense. So this raises questions in my mind. Does the tagging contain a base medium plus the flourecent medium an would it have been possible during the tagging process for the latter to have run out? In this case, could this in fact what has happened in this case? So would this PB qualify as the untagged variety or is that reserved for stamps that have total missed the tagging process?
