In order for humorous street art to be effective, it needs to be well done, and the general public also needs to be able to understand its concept.
Illustrator Ian Stevenson has dipped his hand into the world of graffiti, and he has done this in order to make sure his message reached a widespread audience. Stevenson has found standard city dwelling objects, such as a garbage bin or a brick wall, and used these pieces as his canvas.
His work has a hilarious edge to it, which makes viewers look twice. He has a garbage can asking you to follow it on Twitter, or a dollar bill asking to borrow money from you.
These examples of humorous street art enable viewers to connect with the pieces, and even though they are simple, the message Stevenson was trying to portray is well received.
