Theory says that people unconsciously notice the subliminal message, which triggers an action desired it would by its author. For example, there is a legend theaters used to insert short frames of food and drinks into their movie rolls, hoping to awaken hunger and thirst among audience, eventually resulting with higher sales of their fast-food products. One such subliminal thing is supposedly hidden in Charlie Brown’s portrait. I’m not exactly sure where this came from, or whether it’s just a coincidence, but if you spot it – it should perfectly fit with the title of this article. Happy hunting!
