Trails Plowed Under by Charles M. Russell

I'm helping my late friend's widow sell his book collection. I'll be listing others soon but for now I have for sale a very good condition, including the dust jacket, copy of Charles M. Russell's 1927 first edition "Trails Plowed Under" with an introduction written by Will Rogers. It has my late friend's name written inside the front cover; other than that it is a clean book. The book is illustrated with prints of five Russell oil paintings and fifty line drawings.

I'd like to get $50 for this book, plus postage from Whitehorse, Y.T. (probably around $20.00)

Thanks.
