The four-metre by four-metre card, which is as tall as a double-decker London bus, was created by members of the charity's Crisis Skylight centre, where homeless people and people with homes can take part in various creative activities.
Businesses that donate to the charity's Christmas card budget will receive a short film of the artists creating the card, which can then be emailed to their clients as an eco-friendly e-card. This will be followed up with a special ‘thank you' from Crisis in a double-page advertisement in The Financial Times.
Leslie Morphy, chief executive of Crisis, said: "By simply donating the money that would normally be spent on traditional company Christmas cards, businesses can support homeless people while continuing to wish their clients a merry Christmas."
The Christmas card was unveiled in London's Spitalfields this week.
