Royal College of Art printmaking students are displaying their work in London Tube stations this week. Posters encompassing photography, drawing, etchings, collage, mixed media and digital techniques can be seen in the South Kensington station underpass, and in Charing Cross and Earl's Court underground stations. The project, in conjunction with 'Platform for Art', coincides with the students' degree exhibition, The Show: One , at the RCA, which ends on June 4.
