"Mobile Lovers" by Banksy in England. This piece was sold to a private collector for £403,000. Ch. 2 describes how art is valued and shows "elements of hierarchy" when collected. This shows the evolution of street art from being vandalism to modern works of art and shows how taste for street art has transformed over the years. This work also uses monochromatic colors and contrast to send its message and create the illusion of light from the digital devices.
