I think it could totally be the work of one person.

Remember the pull tabs on soda cans? The kind that came off? People made all kinds of things out of them. Long chains hanging everywhere.

The people that did that sort of thing picked up the tabs everywhere they went. I remember collecting tons of them and spending hours hooking them together.

Then there were the gum wrappers that were folded and put together to make chains and all kinds of things. People did the same with cigarette packs.

My guess is it was just a hobby to collect the bottle caps and this was a way of showing them off.

And yes, I think it is art, the same way any collection is!
