Shepard Fairey teamed up with Saks Fifth Avenue in 2009 to make this effective, thought-provoking (to those of us into meta-social commentary) ad campaign. I find it simultaneously effective, discomfiting, and snark-filled. I don't know how it'll work as a prompt, but maybe it'll bring something up for you.
(Art prompt is something we do on Sundays. I provide an image, you provide an original thought, a little prose, a little poetry, a relevant quote, an association, whatever! Previous art prompts can be found here.)
