Honestly I do not know... but.... In regards to "art" as in art friends of mine are putting up in galleries and working on in their studios, I have seen many installation pieces, multi-media pieces, painting, drawings, etc that utilize commercial products, discarded remains of products (packages, bottles, etc) or images of these products and not one of them has ran into any legal problems. Not that any of that means one thing since I do not have a concrete answer based on fact or law.
