Jaguar's Real Ad Agency Sent Mad Men's Don Draper A Fake Letter
Carrot Creative — Jaguar USA's real-life ad agency — decided to have some fun at Don Draper's expense (and make themselves look extra savvy in the process) by "mailing" a snarky consolation letter to the offices of Sterling Cooper Draper Pryce, offering their "deepest condolences" to Mr. Draper for the fictional company's "recent difficulties in winning the Jaguar account."
Creative, and, considering the fact that I'm posting it here, pretty damn effective as well.
