Original mug book from San Quentin, with some 1600 photographs of convicted criminals. In all but a handful of instances, there are three photographs of each convict – the top photograph in civilian clothing, hair (facial and otherwise), with hat; the middle photograph without hat; and the bottom photograph with head and facial hair shaved, in striped prison garb, with his name, number, age, crime, length of sentence, state or country of origin, and county of residence written on chalk boards behind him. In most instances, the date of his (and a few hers) discharge (or death) is written in ink on the top photograph.
