The Wish You Were Here exhibition offers the chance to see incredible work for a good cause. Help the charity Art Refuge, which provides support for displaced people's mental health and well-being, by entering in the raffle to win some of the work. See more than 150 pieces by award-winning artists at the exhibition as well. The postcard-sized art will be given away to winners on December 4 when the raffle closes. Enter on the Art Refuge website.
