litter on a stick

But when they are enlarged to 700 square feet, raised 100 feet in the air and randomly spread along every street, they become a form of litter—litter on a stick.» —“That ‘Upscale Art’ Quality Claimed for L.A.‘s Billboards Is Actually Litter on a Stick” by Edward T. McMahon Los Angeles Times Aug. 22, 1989. (source: Double-Tongued Dictionary)
