Blue Skin

Herbert, an established businessman, Karlmann, the distinguished son of upper-class parents, and Albert, a sturdy sailor, overcame all social barriers to live out their passion for tattoos together. At a time when tattoos were ostracized and frowned upon, when tattooed people were considered outsiders and criminals. At first glance, the three appear to be middle-class older men in their 90s, but as soon as they take off their shirts, many parchment-like images are revealed on their skin, telling the stories of their lives in snapshots.

There was a trailer...but, it has since disappeared.
