PBS series, Off Book, recently explored the world of logos--their origin, basics, design process and timelessness. Graphic lords Steven Heller, Sagi Haviv, Kelli Anderson (Off Book logo) and Gerrard Huerta (Blue Oyster Cult, AC DC)  are among the elite logo creatives interviewed for the show. Truly one of the most concise and informative pieces on the power and function of logos!
