To celebrate the Wellcome Collection ‘Skin’ exhibit, Caisa (pictured above) wants you to design her a tattoo to be inked live at the show opening. The winner will also receive £100, a free tattoo, their design on 60,000 posters, and a one-year membership to the Wellcome Collection club. To enter the competition and for more details, go here. In Caisa's words, ""I'd like it to have something to do with body organs such as hearts, lungs, guts and blood." The Wellcome Collection ‘Skin’ exhibit is a show that invites the viewer to re-evaluate the largest human organ. From organs to guts, nerve bundles and veins, everything internal will be displayed. The founder, Sir Henry Wellcome collected over a million objects, including manuscripts, carvings, posters, images and a number of body art artifacts including a piece of preserved tattooed skin (below) taken off an executed criminal around 1850-1900.
