Life-long fan Mark McCarthy has spent four decades amassing 282 shirts which were worn from 1926 up to the present day.
The shirts include those worn by City legends Yaya Touré, Fernandinho, David Silva, Kevin De Bruyne, Sergio Aguero and Erling Haaland.
The incredible collection is expected to sell for up to £1 million when it goes under the hammer at Hansons World of Football.
