I think you will need to provide more information than you have given, as I'm pretty sure there was more than one tramp on the streets of the City Centre on the 70's. I wouldn't think it was the one photographed here as this was taken in 1952 and given his chosen lifestyle I doubt if he was still with us in the 70's. It's a photo I have always liked, and I've always hoped that the photographer paid the old gentleman of the road well for his sitting.
We seem to remember this chap had quite a mass of hair and a big beard....and wore a brown/green Mac..
