Larry Hagman’s belongings will be auctioned off by Bonhams’ Entertainment Memorabilia on May 5 in Los Angeles.

The Dallas star passed away aged 81 on November 23, 2012, from complications of throat cancer.

According to Reuters, the centerpiece of the items owned by Larry Hagman is a silver-and-gold belt buckle engraved with the initials of his character J.R. Ewing.

The garish trinket – adorned with four rubies – expects to fetch between $3,000 and $5,000.

There are rocking chairs, walking sticks, costumes, cigarette cases, and a portrait of Larry Hagman by Oenone Acheson.

Speaking of artwork, Bonhams will also auction off Larry Hagman’s enviable celebrity art collection.

He owned an abstract landscape painting by Oscar winner Anthony Hopkins, an oil painting by Frank Sinatra, and the two Michael Jackson scribbles should get $2,000-$3,000 each.

The Bill Belew costume design for Elvis Presley’s ’68 Special should fetch between $3,000 and $5,000.

Among Larry Hagman’s other musical items were an Eric Clapton guitar and amp ($10,000- $15,000) and the orchestral score for I Wanna Be Loved By You from Some Like It Hot ($800 – $1,200).

This auction comes after Larry Hagman’s 43-acre Ojai ranch affectionately nicknamed “Heaven” was sold for $5 million in March.

Larry Hagman was in the middle of filming episode five of 15 in Season 2 of the Dallas reboot when he died.

The 1978 CBS series, originally envisaged as a five-part drama, became a hit and counted millions of fans across the U.S. and in the 95 foreign countries where it was aired.

The original Dallas ran from 1979-1991, dominated ratings, inspired a prime-time soap craze, and gave rise to “Who Shot J.R.?” mania.

Larry Hagman was at the centre of it – and in 1980, 83 million people tuned in to find out just who had shot the ruthless oil baron.
