I asked the old man and got this reply;
Trying to recall,
I always used to stand IN FRONT OF the barriers a few steps up just behind the Kop goal. If you stood behind you had a good chance of being squashed. The kop used to hold 28,000 spectators, I was at the record L'pool gate in 1952 - 62,000 - and with swaying ended up in the far left hand corner, scary. I think we played Wolves in a Cup game I'm sure we won 1-0. Billy Liddell No.9 swopped positions with Cyril Done No.11. (as in home) Wolves complained to the FA that it was ungentlemany conduct. FA said nothing in the rules, from that day teams began to interchange numbers and not strictly 1-11.
Not sure about the picture either late 40's early 50's. The railings in the foreground were part of the enclosure for the boys' pen which held 3,000. No one under 14 was allowed in the ground, I started off there myself. In the top right hand corner of the Kop viewed from the pitch, 6p. admission 2/6p. 30p. in the ground as the lads got older they would climb out at half time and a few got speared on the rails. Not sure whether one died so the club opened it up and allowed kids in with parents. Not sure whether some sort of memorial before being disassembled.
