This photo has the accompanying description:

"Captain AB Nicholas of the Harrison Line's SS Inanda (left) hands the "Victor Trumper" bat, which has been signed by all touring cricket teams since 1902, to MCC Captain Freddie Calthorpe who is invited to add his signature, circa December 1925."

While I'm happy the description might be wrong (as far as I'm aware Calthorpe only lead one international tour and that was to the Caribbean in 1929-30; he only played a total of 4 Test matches), does anyone have more information about this 'Trumper' bat and the significance behind it?
