London, England (CNN)  -- Baloo, Mowgli and King Louie of the  Apes from Disney film "The Jungle Book" all feature in a print by  anonymous graffiti artist Banksy that is expected to fetch up to  $124,000 at auction Tuesday.
The  image was originally commissioned by Greenpeace for a poster campaign  highlighting the problem of deforestation, with the characters  transposed onto an image of a devastated forest. But the posters were  never circulated due to copyright issues with Disney. 
Estimates  for the original work are the highest in the sale, with "Save or Delete  Jungle Book" expected to fetch between £60,000 ($93,000) and £80,000  ($124,000), and another Banksy canvas depicting a tank trampling on  another tank estimated at between £30,000 ($46,400) and £40,000  ($62,000).
These high estimates indicate Banksy's continuing popularity. The  anarchic street artist, who numbers Angelina Jolie and Johnny Depp among  his many fans, is famous for stenciled graffiti on buildings and walls  across the globe, including the controversial West Bank barrier in  Israel.
Bonhams contemporary art specialist Gareth Williams says  the high prices also show the healthy state of the market for urban art,  which he defines as a more permanent version of street art. 
"I  think when the recession kicked in, it was a difficult time for all  contemporary art, but urban art, because it was such a new market, was  badly affected initially," Williams said. The market has "found its  feet, it's got steadier" since then, according to Williams. 
Bonhams  was the first auction house in the UK to mount a sale of urban art in  2008 and has since staged two more urban art auctions. This is the  fourth sale for the house. 
"I think he appeals  to a huge cross-section of people," Williams said. "You've got  contemporary art collectors who love his work, and he also appeals to  people who perhaps haven't really purchased contemporary art before."
And  Banksy's anonymity, Williams said, helps to maintain a healthy interest  in the artist and his cheeky and often anarchic imagery.
Other  works in the sale include a spray-paint-on-board work by U.S. graffiti  artist Futura 2000, part of a set for a 1983 concert by punk rockers The  Clash; and a three-meter long suspended shark made out of reclaimed  metal by artist Tony D'Amico.
Williams said that Banksy,  alongside other street artists, regularly makes commercial work in  addition to his street-based projects. But Banksy's more commercial work  has not been immune to criticism.
Art critic Matthew Collings wrote in London newspaper The Times in  2008 after a previous Bonhams' urban art sale: "What can you get at the  auction? You can be the owner of Banksy's Laugh Now, in stencil paint on  canvas, for only £40,000. It shows a chimp with a sign round its neck  that reads: 'You can laugh but one day we'll be in charge.'
What  would you really be buying? A status symbol -- the work has no value as  art. But owning it would make you modern and clever. Or stupid. It's a  fine line."
Williams says that although it is created for a  commercial environment, urban art is still connected to its roots in the  street, both through the use of the techniques employed (such as  stencil spray painting and wheat pasting) as well as through its  politicized sensibility.
He added that street art is an ephemeral  art form that disappears as quickly as it appears, and that "urban art  is an attempt to redress this by leaving a more permanent legacy."
Art  critic Francesca Gavin, who writes on graffiti and street art, said  that making commercial art is simply a way for street artists to survive  financially. 
And while he may have proven himself to be a sound  investment at auction, in the end, she said, "Banksy's appeal will  always be that he appears to be sticking his tongue out to the  establishment.
"Something that, I think, might seem very desirable even to the most straight-laced individual."
