You mean nobody's reduced it to digital and bootlegged it yet? I guess it was the basis for conflict for a great many movie Westerns.
I thought every library was connected to a grand Library Searcch data base. I've dug up several archaic books when my local Jefferson County Library searched for them. (One was found in San Franciscoi and they shiipped it to my library, no charge.)
To save time for others who don't know what it was all about, from a hit on a duckduckgo search:
"Show Details
Description: San Antonio, TX: Naylor, 1954. First edition. Hardcover. Very Good+ in Very Good+ DJ. 5 1/2 x 8, 158 pgs. This is the story of the Graham-Tewksberry feud in Arizona. When the book was released, the publishers were sued by some of the descendants of the characters involved. Less than 200 copies reached private hands and, today, is very hard to find. Dust jacket price has been clipped."
US$700 seems to be the going price.

"The Pleasant Valley War gave Arizona Territory a reputation for not being ready for statehood."
No , Sherlock.
