Large Queen Paper Types By Duckworth

I trust this is acceptable, since I bought the book for reference in classifying my L Q. Attached are 3 scans showing the various types of paper used. Note the paper 5 which is the one on Watermark stamp rarity that was sold this week end. For more details on paper use, period, rarity, I recommend you check with you library for copy of this indispensable book for any study on Canadian Large Queens,published by the V. G. Greene foundation
