Antiques in Italian Interiors, Vol. I, written in English by Roberto Valeriani and illustrated throughout with beautiful full page photographs by Mario Ciampi, should be on everyone's coffee table.
Vol. II is coming out this year in April, and is definitely on my birthday present list. I can't imagine how he might top Volume I, but with Ciampi on the job I'm sure it'll be worth the price of admission.
For the decorative artist, there are some gorgeous images of painted ornament that are sure to inspire. Until the new book comes out, you can take a look at these from the first one.
