I think that "saying" (n a resume) that you have work in a well-known coropration is not particularly impressive.
"Showing" that you produce good work (via portfolio) is much more impressive.
Long ago, I had a chat with somebody who worked at the Boston Museum of Fine Art. He told me that on a daily basis the museum received unsolicited paintings. This work ended up in the trash. He laughingly told me that people just sent a painting in so that they could say that their work was in the collection of a famous museum.
I am NOT impressed with artists who produce long lists of famous people and institutions who bought their work. I suspect (and know) that some of those lists are padded with bogus names.
But maybe some folks are indeed impressed by big names. The art world can be verrrry silly and pretentious. If you can benefit from playing that game, go for it!
And for pete's sake, let us know if this kind of thing works.
