The picture above is an advertisement for the movie, Pirates of the Caribbean. On the right is a subliminal message of the movie. The skull icon has the shape of Mickey Mouse. This reminds people of Disney. The movie was also made by the company Disney. This wasn't really a bad overt message. This message maybe wasn't intentionally trying to promote their company, Disney. The real message of this advertisement, like every movie advertisement, was to promote the movie. Such like trailers. But because of the shape, many people have the perspective of it as Mickey Mouse, a key symbol of Disney. But there are other advertisements like this that sometimes take shape or there are words hidden in the advertisement. One popular company logo is Tostitos, where there are two people sharing a bowl of salsa. Another would be Toblerone.
