Hi Doug,
If you are in or near Toronto, it maybe worthwhile to pay a visit to the Vincent Graves Greene offices, in particular, their philatelic library (Harry Sullivan Philatelic Library). I am sure this is a topic they have a publication for.
Just a thought.
Thanks smauggie for the information. I will be able to take the train from my place to Toronto then take the subway.
Will go when the weather is nicer and no snow.
Merry Christmas and all the best for the New Year.
