What does this say about the following works?
What do we expect from a photograph? Given what we know about the Nazi propaganda machine, would this have been as effective as a painting or sculpture?
What makes this sculpture so disturbing? What if he had used stone instead? Would it have changed the meaning? What if he had simply painted the image?
Fautrier could hear the Nazi’s executing prisoners from his studio. Fautrier used sand and plaster to build up the surface of this painting, why? Would it have been as disturbing? What was he after?
Noguchi used ribbon slate, which is used in construction to face buildings. What is he saying?
If these were sculptures, not real people, would the meaning change?
This work is made out of junk gathered in New York City. It gave a performance before it self-destructed. What is he saying? If he had made the objects, rather than found them, would the meaning be the same? What about the fact that it blew up?
This is a reconstruction of a bordello. Does the fact that everyday objects are used contribute to the meaning?
Would this have worked as well if it were a photograph? Painting?
What something is made out of contributes to its meaning. The media is an important part of the message.
