Answer: Mixed media art involves mixing different creative mediums to create work that incorporates two or more art forms. For example, you can add sculpture to your painting, or draw on top of photography prints. Mixed media is all about breaking the boundaries between different art forms. Artists need to look at everything as a potential canvas.
The cave paintings are found mostly in mountains in the present-day Mexican state of Guerrero. The Olmecs created mainly sculptures out of basalt. The Mayans made sculptures out of stucco and created pottery out of clay.
