Postal art is a form of artistic expression that utilizes the postal system as a medium. Artists create unique pieces, often using envelopes, postcards, or mail art, to send their work through the mail. This practice encourages creativity and communication, allowing artists to share their art with a wider audience. The movement gained popularity in the 1960s and 1970s, influenced by artists like Ray Johnson and the Mail Art network. Postal art often emphasizes the journey of the artwork itself, transforming ordinary mail into a canvas for creativity. It fosters connections between artists and recipients, blurring the lines between art and everyday life.
