This album cover for Green Day's album “American Idiot” has very punk imagery, and relies on this and it's simplicity to help get its genre across. It has a very standard colour scheme, boasting the red white and black that many punk artists use. The key to this is that by using a colour scheme that older punk artists used, they are instantly recognized as being from the genre of punk. As well as this, their anti-establishment imagery is very obvious too, further helping to define them in the genre of punk.

The image of the man holding a grenade is very politically inclined, but having the grenade heart shaped as well helps to add depth to this very intense picture. The simplicity of drawing helps add to the overall impact of the image, and this in turn helps to draw an audience for sheer principle. A very punk image as well, it attempts to show war and violence as being bloody things, and the heart helps to just show how much governments put into the idea of war.

The fonts used on this album cover are quite normal, except for little cracks visible on most of the lettering. This in itself is again a simple but effective thing for showing the punk genre, as it shows conformity but also an underlying meaning of instability, which reflects the views of most punks.
