It’s actually a photo of 23 year-old Martin Scorsese in 1966, when he was a student at the Tisch School of the Arts. This was roughly a year before he made The Big Shave, the bloody Vietnam-inspired shaving short. Right after that came I Call First, which was later retitled Who’s That Knocking at My Door (’68). I don’t know which was completed or shown first, but I’m presuming Who’s That Knocking came second.
