I've received a few more emails asking where to find Vogue's Book of Etiquette, so I thought I'd remind everyone about the two most frequently referenced editions. Legendary Millicent Fenwick, longtime editor at Vogue and four-term Congress member, wrote the 1948 version. Contemporary Vogue writer, Julia Reed, often refers to this edition; perhaps it was among the pretty stacks of books and found objects when her French Quarter house was photographed for the February 2001 issue of the magazine. (Above, credit Francois Halard.)
I found a 1969 edition at an antique shop. This one has a graphic, more colorful cover and the text deals with social situations that were not discussed in previous versions. There is also an edition from the 1920s. Apart from online booksellers, eBay and vintage shops are good places to find the books.
The image of Fenwick is from millicentfenwick.com and Janet Blyberg photographed the U.S. Capitol. Visit designer Thomas Jayne's site to see more of Reed's house.
