POP ART COMMONLY USES EVERYDAY MUNDANE AND BORING OBJECTS
Pop art commonly uses everyday, mundane, and boring objects as it's subject. Using bright colours and/or taking it out of its natural habitat and into a setting you usually wouldn't see it in. Things painted in the pop art style are usually made to look 2D, but can also uncommonly appear in 3D sculptures etc...
The works are then mass marketed for advertisement purposes for example, music, food, theatres, and general products.
