Have you ever seen a big poster on a wall or a pole when you're walking around your neighborhood or city? Those are called street posters! Sometimes, people who are artists or just really passionate about a message or idea will make posters and put them up on the street for everyone to see.
Street poster art is a type of art that uses posters to express feelings, ideas, or messages. It's just like making a drawing or painting, but instead of hanging it on a wall in a museum, it's put up on the street for all to enjoy and see.
Street posters can be about anything. Sometimes they're political - meaning they have to do with the government or big issues in the world - and sometimes they're just for fun or to promote a concert or event.
Some people believe that street poster art is a way to bring art to the people. It's a way for artists to share their work with everyone, not just people who can afford to go to galleries or museums.
Unfortunately, sometimes street poster art can cause problems for the people who put them up, as some people don’t like to see posters all over the place. However, it is a creative way to express oneself and bring art to the streets!
