Powder Room by David Hicks who worked in the 50's, 60's and 70's. He embraced the Regency- Empire- Neoclassical sensibilities for his time. Like most designers adopting this style he has an amazing sense of color He also invented the word "Tablescape" and turned into an art from.
David Hicks: “It is perhaps I who have made tablescapes… into an art form; indeed, I invented the word,” he wrote. “What is important is not how valuable or inexpensive your objects are, but the care and feeling with which you arrange them.”
