Contrairement à un tirage photo classique qui, exposé en pleine lumière, jaunira après quelques années, un tirage d'art a de surcroit une longévité exceptionnelle d'environ 100 ans. Ces tests de longévité sont opérés par des instituts spécialisés indépendants comme le Wilhelm Research Institute sur la combinaison des encres pigmentaires et des papiers d'art sélectionnés par Artdeqo.
Banksy's works have dealt with various political and social themes, including anti-war, anti-consumerism, anti-fascism, anti-imperialism, anti-authoritarianism, anarchism, nihilism, and existentialism. Additionally, the components of the human condition that his works commonly critique are greed, poverty, hypocrisy, boredom, despair, absurdity, and alienation. Although Banksy's works usually rely on visual imagery and iconography to put forth their message, Banksy has made several politically related comments in their various books. In summarising his list of "people who should be shot", he listed "Fascist thugs, religious fundamentalists, (and) people who write lists telling you who should be shot." While facetiously describing his political nature, Banksy declared that "Sometimes I feel so sick at the state of the world, I can't even finish my second apple pie."
On 18 February, BBC News reported that a recent Banksy mural, known as the Slave Labour mural portraying a young child sewing Union Flag bunting (created around the time of the Diamond Jubilee of Elizabeth II) had been removed from the side of a Poundland store in Wood Green, north London, and soon appeared for sale in Fine Art Auctions Miami's catalogue (a US auction site based in Florida). News of this has reportedly caused "lots of anger" in the local community and is considered by some to be a theft. Fine Art Auctions Miami has rejected claims of theft, saying it had signed a contract with a "well-known collector" and that "everything was above board"; despite this, the local Councillor for Wood Green is campaigning for the work's return.
Pour une bonne correspondance entre votre écran et les tirages que vous recevrez, Il est indispensable d’intégrer votre espace couleur de travail dans vos images: Lors de l’enregistrement de votre fichier, vérifiez que la case «profil ICC» est bien cochée. Sans espace couleur associé à votre image il m’est impossible de savoir dans quel espace colorimétrique vous avez travaillé vos images.
In 16th-century Europe, oil painting on canvas arose as an easier method for mural painting. The advantage was that the artwork could be completed in the artist's studio and later transported to its destination and there attached to the wall or ceiling. Oil paint may be a less satisfactory medium for murals because of its lack of brilliance in colour. Also the pigments are yellowed by the binder or are more easily affected by atmospheric conditions. The canvas itself is more subject to rapid deterioration than a plaster ground. Different muralists tend to become experts in their preferred medium and application, whether that be oil paints, emulsion or acrylic paints applied by brush, roller or airbrush/aerosols. Clients will often ask for a particular style and the artist may adjust to the appropriate technique.
Among the structures photographed prior to the opening were a large pinwheel by Banksy, Horse Scaffolding Sculpture by Ben Long, and a twisted truck sculpture, Big Rig Jig by artist Mike Ross which was previously shown at Burning Man in 2007. Works by 58 artists, including Jenny Holzer, Damien Hirst, Jeff Gillette, Jimmy Cauty and Bill Barminski were featured in the park. Banksy said he contacted the "best artists I could imagine" to exhibit, with two artists turning him down.
