Its 1972/3, because Boro have no red chest band and that is a sparse crowd probably only 6,000. Crowds dropped off that season pretty badly. A lot of low scoring games.
It's the bottom of the Holgate, with part of the Chicken run in the background.
The crowd inside the stadium was policed with police, not stewards.
I don't remember going to the game so the young lad with the dark brown mop hair was not me, but I think I looked like that in 1973.
I have seen the photo at the Art bank in Saltburn. A guy used ot sit on a chair greeting people when they went in, sometimes playing a musical instrument, he was called Robin Dale and I think its one of his photos. He photographed in South Bank.
