I've got a birthday card personally written to me on my 8th birthday, signed by the 78 European Cup side and a pennant signed by the 84 winning team. I've also got a very old Wolves program from when they played us back in the 50s signed by both sides, including Billy Wright, Billy Liddell and Bob Paisley as a player.
I've got a few old 45 vinyl singles from the 60s and 70s. One's a BBC audio of the Panorama special on the Kop and the other is the side singing "We are Liverpool, lalalalaa..." to the tune of Boney M's Brown Girl in the Ring, with 'Hail to the Kop' on the B side. I've also got one of Paisley just reading out his squad with the Kop singing YNWA in the background. I did have the vinyl called something like the Kop Sings, which was basically a live recording of the Kop during a couple of matches in the 70s with no voice over, just the crowd. Sadly that went walkabout from my collection at home some years ago.
Other than that, I got a few on the program after the 83 Milk/League Cup Final against the Mancs and loads of autographs on books, pics, etc. from the 80s. And loads of programs from the 70s/80s/90s. Only non LFC is the Bolton v Blackpool 'Matthews' FA Cup final program and ticket, which was my Grandad's who worked the ground at Bloomfield Road back in the day.
