Parts for Sale: Dealership Paper Collectables

I found these paper documents at the swap meet recently. I don't know if any of you collect these types of things. I have not found too many collectable posts on this forum.

I thought they were cool unique items for a Datsun collector. $20 for the 4 pieces shipped, media mail (in the 48 US States), I have a few sets of them. 

I would ask for friends and family PayPal, as I should't be considered a scammer. If you want the protection of Goods and Services the price will be $22.
