I am not sure what this question is asking but I think the answer is: There are many things that are made by people and used in the past so it could be numerous objects. So I think that the answer is: Paper(not sure just a guess)
The south winning would be a <em>huge</em> issue in itself, and if they continued to use slaves when the Industrial Revolution came around, there wouldn't be a need for slaves, and the vast expansion of the slave trade would shrink by a lot- as the US wouldn't need them.
Here's the problem:
If we're going into counterfactual history, we have to keep a lot of things in mind.
Was the Industrial Revolution sparked because there were no more slaves? If they still had slaves, would it not have been necessary to obtain and invent machines?
Would we be the United States? Would be have gone at war again from the North still being against slavery? Keep these things in mind.
Hopefully this helped!
