Porsche first began as an automobile manufacturer, and quickly rose to fame by making some of the most luxurious cars in history. In the 1970s Ferdinand A. Porsche started his own design company. This design company was created to really express the designs that Porsche had. They specialized in luxury sunglasses, as well as luggage and some apparel. The first models created were the 5620 and the 5621. Often referred to as the most beautiful frames ever created, they embodied the essence of sport and luxury. The aviator type frame of the 5621 pushed the boundaries on what can be done with frames. The 5620 used a racing helmet as its muse and were given a shield look.
