Pieces by Shrigley, as well as Tania Bruguera, Gillian Wearing and Mark Titchner, are rolling out across the Tube network from today on large-scale poster sites and digital displays, incorporating the themes of openness and diversity.
Work from a further six artists will roll out through the summer and into the autumn.
The artwork was commissioned by Transport for London's long-running art programme, Art on the Underground. The launch also sees campaign ambassadors handing out Oyster card wallets bearing Shrigley's design to London commuters.
This is the latest segment of an ongoing campaign by London's new Mayor in response to the UK's vote to leave the EU. The majority of London was pro-'remain'. The campaign has included a number of events, interviews with Khan and social media efforts. Freuds has provided PR support to the campaign.
Khan said: "We’ve asked some of the world’s leading artists like David Shrigley to help us communicate the simple but vital message that despite the uncertainties around Brexit, London will remain an international city that embraces and celebrates diversity, a city where everyone is welcome, and a city that will not cut itself off from the rest of the world."
Shrigley added that the campaign sent out a "clear" message that London was still open to people of all backgrounds. "This campaign is about what kind of city we want to live in – and I’m proud to be working with the Mayor to get across the message that our capital is a place where everyone is welcome," he said.
Earlier in July, Khan urged the capital's creative agencies to help amplify the message that post-Brexit London is open for business, asking for submissions to get to the London Mayor's office marketing team by 22 July. The team is now studying submissions and will announce next steps in the coming weeks, a spokeswoman for the Mayor's office said.
