I wasn't born until 1980 so this is a little bit out of my statto knowledge. Was John Charles at the club in 62/63 in his 2nd stint? That's what put me off. I could easily be a season or two off but I'd be confident it's prior to 1965.
He left us 2nd time in 62. I never saw him play, other than in Jack Charltons testimonial in the mid 70’s, when he’d not played professionally for many a year. He was terrific, I still remember him trapping a ball on his chest, in that game.
Without spoiling Wakey's quiz, the photo was taken in January 1963 prior to our 3rd round F A Cup game at home to Stoke City, which wasn't played until March 1963 due to severe bad weather, meaning numerous games called off throughout the UK
Don't worry Emu I'm only 5 years younger than you and I only recognise Charlton as he looks so distinctive.
