The Bertillon measurement card of Florentino Jaso indicates that he was examined on May 6, 1918. Affixed to this measurement card is Jaso’s prison photograph, known commonly as a “mug shot.” His inmate case file indicates that he was convicted in Laredo, Texas for violation of the Food Conservation Act.
A system of physical identification pre-dating the use of fingerprints, Bertillon Measurements used anthropometrics, such as the length and width of the head and the degree of forehead slope to create an individual’s unique profile.
