[2] Although little is known of his personal life, Cartrain's career supposedly began at the age of 12, beginning with a few small pen tags.
[3]From Leytonstone, East London, he initially worked only in his local area, but "because no one pays any attention", had decided to move on by the age of 15, to the back streets near Old Street and Brick Lane in Hackney, in addition to central London, even spraying on walls opposite the Houses of Parliament.
[3][4] His work often includes depictions of notable mainstream figures such as George Bush and Elizabeth II, Queen of the UK.
These images were later reproduced by Gilbert & George and displayed at their 2014 exhibition "Scapegoating" at the White Cube gallery in London.
[citation needed] In December 2008, Damien Hirst contacted the Design and Artists Copyright Society (DACS) demanding action be taken over works containing images of his skull sculpture For the Love of God made by then 16-year-old Cartrain, and sold on the internet gallery 100artworks.com.
"[8] In July 2009, Cartrain walked into Tate Britain and removed a packet of Faber Castell 1990 Mongol 482 series pencils from Damien Hirst's installation, Pharmacy.
[12] Cartrain has posted a video on YouTube, showing himself putting up a piece of cardboard box as a conceptual artwork in Tate Modern; he states, "I managed to put my cardboard box up in the Tate Modern for two hours without being spotted as a fake".
