I have a couple vintage ones I've been holding onto.
68 Camaro, 69 Camaro, and maybe a GTO one. I have a bunch of them I got from my father. I keep them in page condoms and let people look occasionally. I let one guy look at it, so I pulled it out of the protector and he started thumb-creasing the sides of the page...
I almost freaked and pulled it out of his hand.... Ok that's enough, basically. They're so delicate and barely being held together by the original staples in the center of the pages. They're priceless to me.
