Portrait is generally considered as the representation of a person according to its features and appearance, be it real or in the author's view, so that its identity and individuality are characterised.
In the big cities it has become a common thinking that every person is blended into the mass, which turns into a variegated and unformed aggregate, swallowing the single persons. Every individual is depersonalised and loses its social and cultural identity, almost becoming invisible to the other's gaze.
This is the meaning of these portraits from behind, removing people's expression and disregarding their personality, conveyed through their somatic features, and transforming them into presences alienated from the surrounding environment and from present time.
The names "John Doe" for men, "Jane Doe" for women and Baby Doe for children are used as placeholder names for a party whose true identity is unknown or must be withheld in a legal action, case, or discussion.
