SPORTING mementos take various forms. But how about a bit of sporting history featuring Chris Patten? A tennis racket signed by every player at the recent Marlboro Championship - and that includes Patten and Chief Secretary Sir David Ford, who participated in a pro-am charity game - will go under the hammer on Friday at the Marriott Hotel ballroom to raise funds for Project Sunshine, a charity for mentally handicapped children. Sponsors Pacific Hawk say it is the only racket which bears the signatures of the best players in the world and the Governor of Hong Kong. Also to be auctioned is a pair of shoes belonging to Michael Chang which have been donated by the Marriott. Isn't that marvellous. One minute you leave your shoes outside your hotel room for cleaning, the next they're being offered to the highest bidder!
