Wanted: Vintage graffiti photo collections; magazines; spraypaint - $100 (all city)

Looking for collections of older photos (80s-2000s), blackbooks (sketchbooks), magazines, show flyers, spraypaint of graffiti or street art.
No collection too small! I'll look at one off photos, books, magazines, whatever! Less about gang stuff (unless it's real old) and more about hip-hop/style writing.
