How many porsche factory maroon binders from the 356 era is enough?

Ah, the title of this blog is a trick question.  One can never have enough of the original factory maroon binders!
Below are some photos I have taken from one I just bought from Tom Nelson through the 356 Registry Classifieds Section.  As you can tell, it cleaned up very nicely.
Thanks Tom!
In the bookshelf picture, it is the one next to the Carrera manual.
