A very interesting archive on Fuel.
"This unique archive documents Russian criminals' tattoos and their coded meanings. Included in the collection are more than three thousand tattoo drawings made by Danzig Baldaev during his time as a prison guard between 1948 and 1986. Tattoos were his gateway into a secret world in which he acted as ethnographer, recording the rituals of a closed society. The icons and tribal languages he documented are artful, distasteful, sexually explicit and provocative, reflecting as they do the lives and traditions of convicts."
