Liddell knocked out Blackpool in the 6th round of the FA Cup on Liverpool's way to Wembley in 1950. Willie Fagan took the lead for Liverpool in the 19th minute, but Blackpool equalized four minutes later. As you can see on the cartoon, Phylllis had just given birth to twins David and Malcolm and they cheered on their dad Billy to score Liverpool's winner in the 81st minute.
Liverpool went on to beat Everton 2-0 in the semi-final, but sadly lost to Arsenal in the final, 0-2, where many complained Billy was literally kicked out of the game by the Arsenal players.
"LIDDELL was there at centre forward again to crack home another canon round in the 17th minute. This time the goalkeeper was not within close proximity and the net caught another flood blooded shot. This time the referee took a close inspection of the net as it appeared to be ripped off the hooks behind the bar."
