A bejewelled belt buckle worn by Larry Hagman in the original run of Dallas is set to go under the hammer in Los Angeles.

J.R. Ewing's ruby-encrusted silver and gold accessory, featuring the villainous oil tycoon's initials, is expected to fetch between $3,000 (£1,875) and $5,000 (£3,125) when it goes up for sale at the Bonhams auction house in L.A. on 5 May (13).

It is one of several personal pieces belonging to Hagman, who lost his battle with cancer last November (12).

A leather director's chair the actor used on the set of Dallas and a collection of Hagman's beloved Stetson cowboy hats are among the other lots at the auction.
