Can a private art museum make money? Charles Saatchi’s new London galleryseems to be doing well. “The gallery has had 320,000 visitors since relocating to its new premises in County Hall and opening to the public on 17 April. Ticket prices are £8.50 for adults, £6.50 for concessions and £5 for pre-booked groups. Assuming that just over half pay full price and the remainder pay an average of £6, then, according to our estimate, this adds up to an income of around £4 million a year.”
