Egyptian portraits were carefully wrapped into the mummy bandages and placed in the outside of the cartonnage coffin over the head of the individual.
These portraits were discovered in the 1880s. Painted on a wooden board, portraits proved to be indeed closely resembling the features of the dead people.
It is possible to date some mummies with the help of the hairstyle, jewelry, and clothes worn in the portrait. To identify members of a family by physical similarities became impossible in many cases as most mummy portraits that have survived became separated from the mummies to which they were attached.
