Below is a certain John Hollow Horn Bear, a young Sioux Indian regally photographed taken 1898 from the Digital Public Library of America section of the New York Public Library Digital Collections and downloaded from the MIRIAM AND IRA D. WALLACH DIVISION OF ART, PRINTS AND PHOTOGRAPHS: PHOTOGRAPHY COLLECTION. Other than that, not much else in known about the subject. On the other hand, there was a well known Hallow Horn Bear (1850 - 1913) also a Sioux, and whose short bio can be found in wikipedia.
The details have been nicely captured and preserved all this time. I consider this a work in progress as there are still a few items left uncolored. Perhaps, it can stand as is, but I may have a better disposition to some absent colors in the future.
