An image of the poster appeared on Banksy’s website last Wednesday.
Disturbances broke out in Stokes Croft in April after police raided a squat over fears that a newly-opened Tesco would be petrol bombed.
Proceeds of the sale of the print will go to groups, including the People’s Republic of Stokes Croft (PRSC).
Banksy fans travelled from across the UK and some said they had queued for hours to buy the poster at a book fair in the city.
One told the BBC: “I’m a big Banksy fan, I’ve travelled from Manchester and I just wanted to support [Stokes Croft].
A statement accompanying the release of the image said: “Banksy has produced this fine commemorative souvenir poster.”
The police raid led to a large protest in the early hours of 22 April and was followed by a second demonstration on 28 April.
Officers have arrested 37 people and charged nine over the two protests.
UN investigators say the epidemic was caused by bacteria introduced to Haiti as a result of “human activity”, pointing specifically to the contamination of the Meye tributary system, near the Mirebalais camp housing Nepalese peacekeepers.
The UN had previously described reports that human faecal waste from the camp had caused the outbreak by leaking into river systems as “rumours”, saying sanitary conditions for Nepalese peacekeepers were adequate.
The panel now finds that sanitary conditions at the base, “were not sufficient to prevent contamination” of the river system.
However, Michel Bonnardeaux, a spokesman for the UN peacekeeping department, told Reuters news agency the report “does not present any conclusive scientific evidence linking the outbreak to the Minustah peacekeepers or the Mirebalais camp”.
He added: “Anyone carrying the relevant strain of the disease in the area could have introduced the bacteria into the river.”
The panel experts called for UN peacekeepers travelling from cholera-endemic countries to be screened for the disease and to receive prophylactic antibiotics before their departure.
The investigators also recommended UN installations worldwide treat faecal waste using on-site systems to “inactivate pathogens before disposal”.
The panel concludes the epidemic “was not the fault of, or deliberate action of, a group or individual”.
They say the Artibonite river’s canal system and delta “provide optimal environmental conditions for the rapid proliferation” of cholera.
Experts point to deficiencies in the healthcare, water and sanitation systems in Haiti, saying without these factors “environmental contamination with faeces could not have been the source of such an outbreak”.
Further, Haitians lack immunity to the disease which has been absent from the country for nearly a century, they say.
The results come as medical aid groups in the country raise concerns of a new surge of the disease as the spring rainy season begins.
