Quizplus · Accepted Answer

Cubism, developed by Pablo Picasso and Georges Braque in the early 20th century, introduced collage as an art form. Cubist artists were interested in representing objects from multiple viewpoints and using fragmented shapes and textures to create a new way of seeing the world. Collage, or the use of found materials like newspaper and fabric in artwork, fit well with the cubist approach and became a signature element of the style.
