Spot on Willy Wombat with your call.
The 2nd one along is Jimmy Brown, Harry Gregory had been long gone to Hereford in 1972.
This was I believe the front of a souvenir brochure produced for the league cup final with Norwich.
A similar brochure was produced for the 1971 final with Spurs. My Dad had a shop in Boldmere at the time and organised a raffle with a football signed by all the players. To enter the raffle you purchased the brochure with a raffle ticket stapled to it, in amongst my programme collection I must still have about 80 of those souvenir brochures all with a staple hole in the corner. Also have some photos, certainly one of the ball being presented to the lucky winner. Hope i still have them, if so I will try and look those photos out and post them sometime.
We had a number of the players turn up for the event, it was a carpet and furniture shop and my Dad would have probably let them have some stuff at trade price. I have recollections of sitting in the little office over the shop afterwards with my mom and dad and probably 4 or 5 of the players drinking tea and them chatting about the upcoming final. Chico Hamilton, Bruce Rioch and John Dunn definetely amongst them.
