Bradman wore the cap when he scored the last of his 29 Test centuries against England at Headingley in 1948, and then when he made a duck in his last Test innings against England at The Oval later the same year.
Ganguly can at least console himself with the thought that he, like Sir Don Bradman, scored a duck in his final Test, and after 188 innings his final average was an impressive 42, although Bradman's, of course, was a remarkable 99.4.
