The images by Simon Grennan and Christopher Sperandio were inspired by Bradford, its people, and its buildings and will be displayed as banners on prominent buildings in the city centre until August 8 as part of Bradford Inspired.
Mr Grennan said: "We're delighted to return to Bradford to make new artwork. The four new colour drawings we've made for the city are installed as huge building wraps on the free-standing banner sites from Interchange Station into Centenary Square, the Centenary Square Gallery Building, the Alhambra and the National Museum of Photography, Film and Television.
"The four drawings take as their subject activities and ways of living in Bradford in the 21st century and encompass music, fashion, dance and design.
"They present deliberately aspirational images inspired by David Hockney's late 1960s paintings of the pleasure of experiencing glamour, beautiful people and beautiful places – images that, 35 years ago, he had to leave Bradford in order to discover but which are now widely available in the city every day."
Bradford Inspired is part of Illuminate festival's focus on visual arts. Illuminate is backed by the Millennium Commission, Arts Council England and Yorkshire Forward and Yorkshire Culture. It grew out of the 2008 Capital of Culture bidding process.
