Banana is said to be a fruit that is designed for human beings. The compact size and the shape that fits the hands make banana a portable choice of fruit.
What if other fruits were in the shape of a banana, would it be really fantastic and useful? Imagine durian, pineapple or watermelon in the shape of a banana? The genetically modified organism will answer this in the near future.
However, these pieces of works are not real ads. They don't have any approach in the way the ad works. They are the visualization of different fruits in the banana form presented with print ad visual.
