This head has been reconstructed from 6 fragments that were found near the pyramid of Khefren at Giza. Even though it bears no inscriptions, it can safely be identified as Khefren's, based on the archeological context as well as stylistic criteria.
The shape of the eyes, nose and mouth are reminiscent of other statues of Khefren. The sculptor paid a lot of attention to detail, resulting in a very high quality statue. It is a shame that only parts of the head were recovered.
