Jack Taylor had enormous hands and used to come on to the field holding the ball in one hand, palms up, with no support. He appears to be doing something similar in this photo. Comes with being a butcher I suppose! Linesman is definitely Peter Reeves, ref for one of Crystal Palace's finest nights, their 4-2 promotion win v Wrexham in May 1977, with the two winning goals coming in the last two minutes. What a night!
