Being a collector of books by LL, I have been all over The United States in search of different cover art and am still in search for about six different novels....
I love the cover art so much, that I will buy other versions of the art work for one book. I have a few that I have three different covers, a leather version and a paper back and they all have another illustration...
In my search, I don't think its from 'Crossfire Trail', unless its one I hadn't seen before.
(wish we had photo capabilities)
What I did find is about as close as I can Get is from 'The California's'
I hope this will help you...
Thanks my friend for the search which I enjoy doing....
