Writing on the walls dates back
to cave men days !!!
30,000 BCE – Caveman places first drawings on the
walls of his cave. Most of these depict hunts and the delivery of meat to other
cave people.
According to historians, prehistoric people used natural
objects to paint the walls of the caves. The cavemen used sharp tools or a spear
to etch into the rock . To paint or color they used berries, clay, soot, or charcoal.
The tools used to apply the paint were made by attaching straw, leaves, moss,
or hair to sticks. They might have used hollow bones or reeds to spray the
color on, similar to an airbrush technique.
