The Image below is a colourised version of an iconic picture known as Migrant Mother taken in 1936 by Dorothea Lange, it shows Florence Owens Thompson and three of her children. The black and white original is incredibly powerful and a high resolution version is available from Wikipedia. As an image it immediately says to me Grapes of Wrath.
This colour version is new to me and is a combination of being believably contemporary, because of the colour, and being timeless because of the anguish on Florence Owens Thompson's face.
