Avatar: A black and white picture of Katharine Hepburn starring in the 1936 movie "Mary of Scotland", where she's dressed in period 16C clothing, including a jaunty wee bonnet.
Background: A section from a painting called "The Great Day of His Wrath" by John Martin, which depicts an end of the world scene, featuring what appears to be two large land masses being torn apart, with a dark abyss leading up to fire and magma.
