Pictures of objects

So, I started sorting those photographs I found trying to think about categories that might help me understand the Rauschenburg painting I found. These photos seem to be talking about materials.

Do you know what made this strange thing? It looks really delicate.

I know what this one is, a human skeleton! In the future we relate them with death and learning. How does this relate with how your time sees them? What do skeletons mean to you?

Here in the future we have very different looking animals, I don't think these bones could have come from any of them!

What kind of animals do you think these bones and wings may have come from? 

Do you have any associations with those animals? Do they symbolize anything?

What could a Crow or Raven symbolize, like the black bird attached to "Canyon"?
