The Hepatitis C Trust, a U.K. advocacy group, recently commissioned more than 200 artists for an awareness campaign and fundraiser for the hepatitis C virus (HCV). The auction event, called “Art on a Postcard,” ended up raising £42,208 (about $66,000), according to the group’s Facebook page.

For the event, British artists donated one small postcard-size artwork to be auctioned off online. Among the famous artists who contributed were Damien Hirst, Gilbert and George, Harland Miller, and Marc Quinn, as well as many others.

The cards represented a number of different artistic styles, including street art, photography, digital art and illustration. They were displayed online and at London’s Whitfield Fine Art Gallery from November 11 to 13.

Each postcard was then auctioned off online. The event was set up so that bidders did not know which artist made which piece of art until after the auction had closed. All proceeds benefit the Hepatitis C Trust.

According to the group, money raised from the event will go toward diagnosing people who do not know they are living with hep C, supporting those living with HCV, and ensuring that the disease is eliminated within the next 15 years.
