I've been talking with the owner of this blog, and asking his advice on how to organize my stamp albums for a semi-specialized collection of Canada, especially the early issues where Unitrade can be somewhat opaque as to what exists.
The author today posted an amazing summary of the Large Queen issue that I think everyone who has an interest in this short-lived but complex issue should check out, it is a veritable GOLD MINE of information.
