Answer 1

Answer: The cartoon

Explanation:
Before painting on a wall (creating a mural), the artist creates a large drawing of the work called a cartoon.

The cartoon was positioned on the wall, and charcoal was forced through the pinholes onto the wall. The pinhole markings on the wall guided the artist in completing the mural.
