|Example of Forest Kirkland's original watercolors of pictograph panels at Painted Rock Shelter in a small side canyon of the Rio Grande near Comstock, Texas. Most of these figures are of the Red Monochrome style. Kirkland made these "copies" as he called them, on July 13, 1937. As subsequent recorders have learned, copying rock art is a subjective processwhat is copied depends on lighting, humidity, condition of the pictographs, and the eye and skill of the beholder.
