Wert, I got out my box of booklets to check my 586b
and copy is clean as a whistle.

I tend to agree with you that the blue Queens are too far
away from the red Pearson (fitting colour for him)
and the orange Macdonalds (whose colour should have been blue)
to be too much affected from any bleeding.
On the other hand you with print experience would know
that even by combining the 3 primary colours,
yellow, cyan & magenta you get maybe a deep dark brown muddy
colour but not a real black like on the Queen's hair.
I doubt if combining blue, orange and red would give you black.
So where did it come from?
BABN didn't print any Canadian black engraved stamps around that time.
The only black stamp from that caricature definitive series was the
5c Mackenzie King stamp but it was printed by the CBNC.
Anyway your flyspecking leads us many times into some
great discussions which is fun for all of us.
Keep it up wert
