I can tell you exactly how long I've had this https://pbase.com/image/164478763 Porsche key leather pouch. 1975, when I purchased my Grand-Prix white 1974 Porsche 911 Carrera from MaxDial Porsche/Audi in Brentwood, CA? The goofy key leather pouch was included with the car. Please ignore the 'visual-aid key', those appeared a bit later.
