On this episode of HOT ROD Unlimited, we look back at the unique relationship between Carroll Shelby and the flagship magazines of Petersen Publishing -- HOT ROD and Motor Trend. We visit Bob D'Olivo, the publishing company's longtime director of photography and a close friend of Shelby's, who gives us a rare glimpse at his personal archive of Shelby photography. You'll also hear from the magazines' current chief content officer and our executive producer Angus MacKenzie as well as from HOT ROD's publisher Jerry Pitt and Editor In Chief David Freiburger. Finally, we revisit the very last video interview that HOT ROD magazine had with Carroll Shelby, where Shelby reflects on his longtime friendship with Robert E. Petersen, founder of HOT ROD and Motor Trend, and reveals the crucial role Petersen and his staff played in the development of the Cobra.
