AH, Provenance. If we only could prove it on everything that passed our sight; track each owner and how, when and where it became to be but this is not art. It is my belief that if there was a fair account of a man's description in print during that person's life then a fairly accurate sketch could be done. I reside in the heart of the country where Hildebrand was born and speak to people frequently who have a story to tell of him. No provenance, but I will agree that there is not a proven photo of him and there never will be. I own your book, Kirby, and have passed on about fifty copies to friends, libraries and visitors in the Mineral Area. Those who see it, identify Sam with the photo it contains.
