You may have seen something similar on optical illusions sites: Giuseppe Arcimboldo, a 16th century Italian artist, painted similar imaginative portraits made entirely from fruits, vegetables and flowers. However, these are by Klaus Enrique Gerdes, a New York City photographer, who has created a series of similar portraits made exclusively from natural ingredients. As an achievement, I rate this even higher, as you do not have the advantage of artistic liberty and are stuck with what nature is supplying in terms of shapes and colours. First seen
here.
