A pixel-accurate reproduction of saving booklet ( KdF-Wagen Sparkarte) optionally with stamps documenting your pre-payed contribution. 
You can have the booklet filled out (on a German period typewriter), or blank. Additionally you may get stamps - 10 to paste into your new booklet, or the whole sheet of 50 for magnificent display!
You can get more stamps (also special stamps for transportation or convertible) here.

One could get the car by subscribing at Kraft durch Freude (KdF) and prepaying / saving at least RM.5 a week. For each RM.5 you would get a stamp for the savings booklet. 5 booklets later, the car was yours and you could hit the Autobahn!
It started in 1938 as a noble Führer's idea to allow any German worker to own a car. Hitler set a cost limit to 1000 RM (around 5 monthly salaries of qualified factory worker) and Ferdinand Porsche design it to fit in this budget. To learn more about the history, check my dedicated blog post.
