I've deliberately used a wide shot here so you can see the art work in relation to the surrounds. Top right you can see two of the major characters used by El Bocho, one of the melancholy looking girls known as "Citizens" and further right, "Little Lucy"
The beanie of the girls head says "Liebe in Beton" ( Love in concrete?), and most of these fugures have similar sayings.
Little Lucy on the other hand is based on a Czech TV show called "Little Lucy – Fear of the Street". Her hobby is killing her cat and here you see her pulling it apart.
