"The majority of the prison tattoos represent connections between the convicts. Besides gestures and mimics it is a kind of secret code - revealing why 'informative' tattoos appeared on uncovered body parts: face, neck or arms. The collection was created with a view to deciphering the code - among prisoners known as a 'pattern language'. By looking closely at the prisoners' tattoos, their traits, temper, past, place of residence or the criminal group in which they were involved could be determined." - Steven Perez from Bookmarklet
