Meet Skip Gallery, a pop-up art space with a difference. Their MO? Exhibiting works out of, you’ve guessed it, a skip.   For the month of March, this moveable maverick has found itself a very special, if a little unexpected home. Tucked in between Gucci and Chloe on the ground floor of Selfridges, this yellow skip is swapping out rubbish for riches with works from some of the best emerging artists of today.
