Celebrated ad man Richard Kirshenbaum, the original New York observer, reveals the fashions, foibles, and outrageous extravagances of the private-jet set

Paid friends. Pot dealers draped in Dolce. Divorce settlements that include the Birkins at their current retail price. Air kisses, landing strips, and lounge-chair bribery.

For most of us, the idea of life inside the golden triad of Park Avenue, Sagaponack, and St. Barths is just as exotic as the mysteries of the Bermuda Triangle. Luckily, Richard Kirshenbaum has a VIP pass to the Upper East Side and is willing to share the wealth—of gossip. His New York Observer column on uptown social life provides a fascinating glimpse behind the gilded curtain into the swanky restaurants and eye-popping vacation destinations where the 1 percent gathers.

Isn’t That Rich? features highlights from Kirshenbaum’s monthly column as well as several brand-new essays. From cash-strapped blue bloods willing to trade their good names for a taste of nouveau riche treasure to the fine art of donning a cashmere sweater in Capri, our intrepid correspondent exposes the preoccupations of the posh. His insider sources may be anonymous, but “his up-to-the-minute portrait of today’s 1 percent is both insightful and a joy to read, no matter what tax bracket you’re in.” (Mortimer Zuckerman)

Richard Kirshenbaum is one of the most exciting personalities in New York City advertising. In 1987, at age twenty-six, he cofounded the Kirshenbaum Bond + Partners agency, which pioneered such innovative concepts as the pop-up store, sidewalk advertising, and other forms of high-visibility guerrilla marketing. At the time of its sale, KBP was the largest independent ad agency in the United States, with one billion dollars in billing. In 2011 Kirshenbaum launched NSG/SWAT, a high-profile boutique branding agency that works with entrepreneurs and emerging companies. He is also cofounder, with music icon Chris Blackwell, of Blackwell Fine Jamaican Rum.

Kirshenbaum has lectured at Harvard Business School, has appeared on 20/20, was named to Crain’s New York Business’s “40 under Forty” list, was inducted into the Advertising Hall of Fame in 2000, and snagged second place on a list of the top one hundred US entrepreneurs. He is the author of the business book Under the Radar; the relationship guide Closing the Deal, which has been translated into nine languages; the advertising memoir Madboy, an Amazon bestseller; and Isn’t That Rich?, a compilation of essays from his New York Observer column. Kirshenbaum is an accomplished playwright, and his work has been produced by David Mamet’s Atlantic Theater Company. He has also contributed to Us Weekly’s “Fashion Police” feature and has written comedy for the legendary Joan Rivers, among others.
