Iconography and imagery have been used by humans for tens of thousands of years. Humans were using tools for cave drawings as early as 73,000 years ago according to a group of archaeologists, led by Christopher Henshilwood. Their findings were of a symbol resembling that of a modern-day hashtag. This finding was not unique, as many others have surfaced in different parts of the world, thousands of years apart. While neanderthals utilized crude tools such as hand-stencils, modern artists may utilize Adobe Creative Suite, architects drafting software, physicians MRI imaging or X-Rays, and mechanical engineers computer-aided design software to design three-dimensional images of potential products. We have certainly come a long way.
