The UK's most notorious prisoner has created new art in his bid to be released.
Charles Bronson's drawings are poised to go on show and there prices range from £700 to £30,000 for a set of several images.
In many of them Bronson gives an insight into his own life while he has spent 47 years in jail.
The images could also be used to boost a parole bid.
Oliver Hammond artist and curators said: "If we can show that Charlie does genuinely want to be released from prison to work on his art, there's definitely a good chance this can help with his parole.
"You know, why would someone, after creating the works that he's created behind the cell door, not want to continue that on a larger scale outside?
"It's a little bit grim, but it's grim to be in solitary confinement for 27 years and in prison for a total of 47 years. This is a man's mind depicting his grim life."
Now known as Charles Salvador after his latest idol, the late artist Salvador Dali, he has been drawing for decades and his art has raised cash for various charities.
Then called Bronson, he was jailed for armed robbery in 1974 and has been in prison since then because of repeated violent outbreaks in jail which has mostly been aimed at prison staff.
Peter Kirkham a former Metropolitan Police Flying Squad detective questioned whether prisoners should be allowed to make money from their notoriety
Sky News reports the detective said: "His life is his life and if someone wants to pay money for some version of that, then it's up to them.
"But it scares me to say it, but how long before we see someone like this as the new guest on Big Brother? It's wrong, because people simply shouldn't gain from their crimes, directly or indirectly."
A Parole Board will decide if Bronson is a risk to the public and if there is low risk he could be freed him.
Experts also say ability earn money as an artist and support himself, could also help Bronson's parole bid.
Charles Salvador's exhibition will be held at the Henarch Galleries in Spitalfields, East London.
It is expected to open on February 23 but his 'cartoonish' drawings will be available online from today.
The exhibition will feature 'vivid digital images' which have been created by Hammond and inspired by Bronson's artworks, writing and interviews.
The work is sold as non-fungible tokens (NFTs) which are proof of digital ownership.
The Born For Art Foundation set up by Hammond and one of the prisoner's supporter will be receive third of the profits.
The organisation hopes to supply art equipment for underprivileged children.
The Mirror reported last month how 69-year-old inmate is expected to appear before a public parole hearing in March.
He is demanding the hearing is held in the open so he can prove he is no longer a danger to the public.
And now an online fundraising campaign is underway to raise £32,500 for Bronson so he can buy a caravan for life on the outside in Devon.
In an online post it stated: “On March 6, 2023 Charles Bronson (now known as Charles Salvador) will be standing in front of the UK parole board with the hope of finally being released from custody and given the chance at freedom that he so much deserves.
“Charlie is no longer an aggressive criminal, he is a born again artist who has spent the majority of his prison life in segregation doing his artwork.
“He has not been violent or aggressive for nearly 10 years. He is 70 years old in a few months and just wants to get out of prison and enjoy his remaining years as a pensioner, living in a caravan in Devon by himself near his family.
“I am organising a fundraising campaign to pay for Charlie to buy a caravan in Devon when he is released from prison, hopefully on March 6, 2023."
