The exhibit will be showing at the Heartbreak Gallery, and is part of a larger Icons gallery exhibit featuring other celebrities (mainly English) that Ms. Williams had photographed during her career as a freelance photographer. You can read more about the Audrey set in particular here, and if you're in the London area and would like to drop by for a look, you can find the address, hours, and other particulars here. There will also be limited edition signed prints for sale.
I wanted to fly out and see the exhibit myself but sadly, it's just not an option (especially since I'll be traveling to cover Breakfast at Tiffany's in New York). If you're like me and can't make it out to see the exhibit in person, the gallery is offering a nice e-catalogue to look through.
She seemed so tiny and fragile. The room was filled with roses and was ornately decorated. Roses, gilt and gold. She was in that exotic room like a precious bloom amongst all the flowers. - Angela WilliamsThank you to Laura for bringing this exhibit to my attention.
