A WZZM-TV crew spotted the signs Thursday along the highway in Coopersville.
The gun on an ad for a weapons seller appeared to be pointing at the child on an ad for a nonprofit that collects food donations.
Mark Sherwood, regional manager for Lamar Outdoor Advertising, said the misplaced images went up about two weeks ago without attracting attention. He notes, however, that "sensitivities have been heightened" following last week's Connecticut school massacre.
Sherwood said the gun ad was taken down Friday and the company is taking steps to ensure such ad placement doesn't happen again.
