Before/After N. America's oldest art work
The art work at the top is considered by Archeologist to be the oldest in North America. It is located in Kelly Cave 41VV165 about 100 yards up Mile Canyon off the Rio Grande. It has faded so bad from weathering it is hardly visible, Top. On bottom I converted it to lre by stretching the colorspace in ImageJ/Dstretch which enhances red and making the artwork more visible.
