The first picture below is a bronze statue modeled off of the second picture. This is a statue at the Ohlone College in Fremont. It was largely funded by a local bank of Fremont. It's a picture is the oldest painting of the local Bay Area tribes, including the Coast Miwok. As you can see they don't really resemble each other and as a matter of fact the Statue doesn't really resemble modern day (last few hundred years) Ohlone.
Art is unique in its commemoration techniques!
