Yours for £2,000, oil paintings by the Kray Twins (currently owned by a ex-convict who won them in a card game)

But it appears Ronnie and Reggie Kray also had a more sensitive side – as landscape painters.

These oil canvasses by the infamous twins, painted after they were both jailed for 30 years, are to be auctioned in London this week.

The one of a white cottage next to a road was painted by Ronnie. His brother's is an image of a river running through a green valley with an ominously dark sky in the background.

Both twins began painting after their 1968 trial at the Old Bailey, often creating the same scene in picture after picture.

A spokesman for Chiswick Auctions in West London, where the paintings are being sold, said: 'The same themes are repeated over and over again in their work, with very little variation. We expect these two to go for between £800 and £1,500 each.'

Both pictures are being sold by a former inmate who won them from the twins during card games in jail. The auction house spokesman said: 'The seller has given us some interesting insights into the Krays' minds.

Dream house in the country: Ronnie Kray's

'He says Reggie always, always painted with a dark sky. This might reflect his state of mind and the dark thoughts he had. He was known for his moods and being aloof. Ronnie, on the other hand, always painted a white cottage because that was his idea of a dream house, a place in the country.

Ronnie's paintings are more aspirational, whereas Reggie's tend to reflect his sombre state of mind.' The images were painted in oils on to card. They are both eight-and-a-half inches by 11-and-a-half inches.

A similar painting by Ronnie sold at an auction in Lincolnshire in 2005 for £2,200, twice the expected fee.

The spokesman added: 'The seller told us paintings were used in games of cards as currency. If they were by Joe Bloggs, they wouldn't be worth £5.'

The Krays ran a brutal gang known as The Firm in London's East End during the late Fifties and Sixties. Revelling in their image of sharp suits and flashy cars, they began to believe the law could not touch them.

That bravado allowed Ronnie to walk into the Blind Beggar pub in Whitechapel and shoot dead George Cornell in front of customers for calling him a 'fat poof'.

A year later, in 1967, Reggie stabbed Jack 'The Hat' McVitie to death in a flat in North London.

But Scotland Yard closed the net and the twins were given life sentences and told they must serve at least 30 years.

Ronnie died of a heart attack in 1995 after collapsing in his cell in Broadmoor. Reggie died in jail in 2000.
