Embroidered with the England badge and the legend Yug 1950-51, the silk interior has a stitched label hand-written in blue ink Ramsay, size 7 1/8.
The cap was awarded for the England v Yugoslavia international friendly held at Highbury on November 22, 1950, a game in which Ramsey was captain and ended in a 2-2 draw.
Ramsey – who later managed England in the 1966 World Cup – played for his country 32 times, captaining the side three times and scoring three goals.
After his ending his career in football in 1979-80 he retired to Ipswich with his wife Lady Victoria Ramsey. As documented in a letter sold with the lot, this cap was acquired directly from Lady Ramsey by the current vendor while working as a painter and decorator at her home.
At the auction on September 10, it was bought by a phone bidder, a “private individual from Ipswich who had known Sir Alf Ramsey in his later years”, said LSK specialist Glenn Pearl.
