Signed by the late, great Arsenal and Wales goalkeeper Jack Kelsey back in 1957.
The 1957 event was the 31st Schoolboy’s Own Exhibition.
This was an annual exhibition which took place in London, with exhibits ranging from model boats to Vulcan bombers, with a whole host of sporting stars also on hand to inspire the next generation.
Kelsey retired from football in 1963 after suffering a back injury playing for Wales against Brazil the previous year.
