The 1st Dibs floor in the New York Design Center is one of my favorite design shopping haunts. The vendors showcase a curated and eclectic mix of antiques from the 19 C. to the 1980's, many with an emphasis on mid-century pieces. Even if your aren't in the market, there is great "eye candy" and design inspiration to be had.
I found myself drawn to the Sputnik chandeliers. One of the most quintessential mid-century light fixtures, the Sputnik light features a space-age star burst pattern with sleek, contemporary arms. Named for the 1950's Soviet satellite,the fixtures atomic-age design made it popular in the 50's and 60's and today's resurgence for Mid-century design has the darling Sputnik dangling from chic foyers and dining rooms everywhere.
If you can't make it to 1st Dibs, Jonathan Adler's Sputnik inspired chandelier is a classic take on this favorite.
