Drivers heading west on the Pennsylvania Turnpike can see an amusing billboard from Marks Jewelers of Montgomeryville, Pa. In between the Willow Grove (No. 27) and Fort Washington (No. 26) exits is where this particular billboard lives. Its simple message lets you know that the cool jewelry in the ad can’t be found at a chain store: “The mall doesn’t have it. We checked.” This ad is a winner in my book because it’s funny, to the point, and easy to remember.
