Marty Schwimmer asks the question we’ve all asked ourselves at one point or another: “Are There Donut Lampshades In Your Background?”
If you operate a business in some sort of public space, such as a restaurant, and you utilize a furnishing or a decoration that may contain a copyrightable element (such as a lampshade, or a wallpaper or a poster), then your use of such an item may constitute a public display of the work, and if the item is infringing, then you may have some exposure for copyright infringement.
That’s a good bit of advice. Read the piece to see what he means.
