As the only freestanding midcentury specialist in Atlanta, City Issue is Mecca for local Mad Men fans. A full-time vintage dealer since 2000, owner Jennifer Sams has enviable knowledge of the modern design movement and cross-country experience with finding exquisite pieces. I photographed her Inman Park shop and asked her to dish on topics to titillate the growing mass of midcentury style seekers: her favorite cities for antiquing, the best buys for starting a collection, and more.
