Street poster art is a kind of graffiti, more specifically categorized as "street art". Posters are usually handmade or printed graphics on thin paper. It can be understood as an art piece that is installed on the streets as opposed to in a gallery or museum, but by some it is not comprehended as a form of contemporary art.
Viral diffusion of messages and the ability to reach every part of society are core concepts for street poster artists.[1]
