A van with advertisements for beach amusement items parked on the sand.
A van covered in ads for frisbees and beach balls stands unlocked on the beach
There may be advertisements on the van, but that doesn't necessarily mean that the van is covered in them. The ads on the van aren't necessarily for frisbees and beach balls. Just because the van is parked does not mean it is unlocked.
