Using the BNAPS study group's perfin list, I began making album pages for this topic. Now that I'm up to the letter "C" I'm now finding that Canadian National Railway will take up over 100 pages just in itself. I guess it might be something to keep me busy over the winter. On the downside, I only have a small quantity of Canadian perfins in my Canada collection.
Note that the clip I made of the sample album page altered the text in each space. They really look a bit better than shown full size.
