Retro style onomatopoeia in pop-art form, use of this theme is abundant in old comic books. Although childish, the "sound-words' create a playful image and a way to visualise the sound in an otherwise silent environment.
I pinned this from Joshua Corona. This image is of the Joker, and his face is made of us a quote of his "Why so serious?" I like the graphic design perspective and how the typography is used to give his face and hair shape.
