Street artists are individuals who create art in public spaces, often using walls, sidewalks, and other urban surfaces as their canvas. Their work can include various forms of visual art, such as graffiti, murals, and stencils. Street art is often characterized by its accessibility, as it is available for everyone to see and experience without the need for a ticket or entry fee. Many street artists aim to convey social or political messages through their work, making it a form of expression that can provoke thought and discussion. Some well-known street artists include Banksy and Shepard Fairey, who have gained international recognition for their impactful pieces. Street art can also enhance the aesthetic appeal of urban environments, transforming dull spaces into vibrant showcases of creativity.
