This is the Wicked soundtrack cover, for the songs from the stage show.
The cover shows the 2 witches, the one in black the 'wicked' one and the one in white the 'good' or more innocent one. The cover's title is also on the side of the 'Wicked' witch also suggesting her evil. This is contrasted by the whispering of the 'good' witch, as the picture suggests she maybe helping her or spreading gossip. There are also small images of flying monkeys on the 'wicked' side, relating to the Wizard of Oz. The 'wicked' side of the cover also takes up more room than the 'good' side, showing the witch's importance to the plot of the show and that it's named after her.
