Junkopia (1981)

One day, at the stroke of evening, on Emeryville beach in San Francisco, where unidentified artists, leave, without anyone knowing, sculptures manufactured with items that have washed ashore from the sea.
This includes a short introduction by arte, approx. 1:12 secs long, with the film being around 6 minutes itself....there are 2 intertitles in the film itself, giving the latitudanal and longitudanal co-ordinates of the beach. No subtitles required, but ill work on some anyways.
