It's for people ("today's lucky 10,000") who might have heard of "Queensbury rules" as a general term for fair play but didn't know about boxing or what a Marquess is or about the connection with Oscar Wilde.

The bit about his eldest son adds some depth to his character and context to his conflict with Wilde.
