As a vintage seller, collector, and buyer, I am still learning so much every day about the wonderful world of vintage. I first spotted these books at B&N (Barnes & Noble) and I've been back a few times now to browse through them and decided I might as well just purchase them because they are great for reference and great just to look through.
