The trend of one line , or line art, is slowly emerging. The first most telling examples date back to the 19th and 20th centuries, with the famous French painters Matisse and Picasso. These geniuses of the brush were able to demonstrate that we could represent and express great things while reducing a drawing with a few strokes to its simplest expression. For artists, it is a way to simplify the complex world around them while communicating a powerful message.
