In some instances we can identify multiple images created by the same hand, adding up to a body of work, something expected of a professional artist. One good example is the panel known as the 3-Princesses near Cub Creek in Dinosaur National Monument, Utah. These three Fremont anthropomorphs exhibit every indication in style and technique of having been produced by the same hand.
Nearby the 3-Princesses, on the cliff face at the Cub Creek site, are a few other instances of multiple images that give every indication of having been produced by the same artist.

What this implies is that the artist that produced the high-quality panel that we admire must have produced many lower quality images while working up to that level of ability. So instead of a large number of creators producing the large number of images at Cub Creek, there may have actually been relatively few artists, each producing a range of images from poor to high quality while practicing their art. This question does have serious implications in the study of rock art as it goes directly to the question of who created it. Was it a large number of people, each making one, or at most a few images, or was it a small number of people, each creating a larger number of images while perfecting their art?
