English: This image is taken from a UK underground newspaper called 'Ink' from 1971. It is the Gay Liberation front cover of that issue. The magazine is defunct, authors and artists unknown.
Underground magazines were usually run as collectives, and most closed down by 1975 through prosecutions, so ownership and copyright of material is unclear, as nobody seems to own it. They were produced in the same spirit that gave rise to free distribution licences, but these came after, and they tended not to have any copyright associated with them. So, they could be considered as precursors to what has become known as free distribution material.
