English: Remark: William Henry Jackson (1843-1942), the owner of this photo published it (showed to public generally) during his life. He wanted this photo to be in public domain. On September 24, 1941, Elwood P. Bonney had written about William Henry Jackson’s wish “to keep Clarence in bounds – to keep him under control”, and further: ”He seems to feel that Clarence will undoubtedly dispose of for cash everything he can get hold of without regard of his father’s wishes, particularly as to preservation of certain items by their disposition to proper Public Libraries, Historical Societies etc where they will be properly protected and of the value they will be in the future to students of history. He said his family never took any interest in his work from the historical view-point – or if there was any such interest it was very little.” (William Henry Jackson, Colorado History, Number 4, ISSN 1091-7438, Colorado Historical Society, 2000; p.139.) Clarence mentioned in quotation above was Clarence S. Jackson, a son of William Henry Jackson (1843-1942).
