For anyone interested, there is a campaign currently on Kickstarter to publish a book covering assorted Porsche advertising from the 1950's to the early 2000's & contains reproductions of over 500 Porsche print ads.

The book is finished and a printer secured, the funding is solely to cover the cost of production. There is also a video showing the layout digitally. It moves quickly, but if you pause the video you can see the potential finished book.
