I was told there were only 11 existing copies of this book remaining - but 9 of these are microfilm and not a "real book", and this includes the one in the British Museum. I can not find the remaining two to see if they know the value.
There were various editions of this made and this was a first edition, (in Cree). Can anyone tell me how much it is worth and where I could sell it? Thank you.
