#15: The Golden Arches Got Spooky
McDonald’s barely changed anything here, and that is why the Halloween billboard works. The familiar golden arches sit on a plain red background, but two tiny ghost faces turn them into a pair of cartoon spirits. It is instantly recognizable, festive, and surprisingly cute for such a minimal design.

There is no complicated joke to decode. The brand uses one of the most famous logos in the world and gives it just enough of a Halloween costume to make people smile. Sometimes a billboard does not need more words, more graphics, or more drama. Two little faces are enough.
