This map was handrawn by J. Evetts Haley after speaking with Charles Goodnight illustrating the cattle drives done by Goodnight and his partner Oliver Loving. You might recall a fictional account of the story of Goodnight and Loving's third cattle drive in the Lonesome Dove series. The map was lost for several years in Haley's copious collection of papers until reportedly recovered around 1980(?). The map was sent to an unamed University for restoration and 100 copies were produced and sold. This is the original.
Goodnight was a character and inventor of the Chuck Wagon. I admire him for traveling hundreds of hostile miles to deliver his buddy Loving's body back to Weatherford, Texas to be buried. That is true and lasting friendship.
