Here is a nice find for Porsche lovers. This is a 12-page brochure from 1989, featuring Professor Porsche's philosophy, along with a brief look at Porsche history. There was originally a series of these, and I think they were magazine inserts at the time. From my personal collection and stored since new, this is in excellent vintage condition (some very light scuffs/creasing from storage). A great addition to your collection!
