From "Family Tree" (2001) by Zhang Huan —
Zhang Huan's performance piece "Family Tree" uses his own body as a site to explore social phenomena. Calligraphers slowly coat his face with phrases, from political slogans of Mao Zedong to observations about Zhang's skull. The sequence tugs at the tension between the self and society, letting viewers ponder at what point one supersedes the other.

From "Criminal Photographs No.19" (1880s-90s) by an unidentified photographer —
In the 19th century, French criminologist Alphonse Bertillon created a method of measuring the front and profile headshots of convicts, creating the groundwork for the modern mugshot. Individually, the images tell only surface-level information about the subjects, but as a collection they reveal how photography was used to develop a visual language for criminality.

From "Faces and Phases" (2006-14) by Zanele Mulholi —
