American Prison Tattoos is a photo story by Robert Gumpert that explores the meanings behind prisoners’ tattoos in Californian penitentiaries.
According to a 2006 PEW Research Center report, almost 4 in 10 between the ages of 18 and 40 are tattooed. Tattoos may be becoming the norm but before their surge in popularity, tattoos were the province of society's outcasts: sailors, artists, carnies and outlaws – acting as road maps of their lives: who they were, what they had done, their loves, desires, their sorrows and pains.
