I am trying to get my hands on early Trek brochures (I want the actual brochure not a PDF I can get off vintagetrek). I never see these on e-bay. Anyone have any or know where I might look?

I see them appear on eBay sometimes. Just do a search in: SPORTING GOODS > CYCLING. I have eBay notify me when anything under the search term: "(brochure, catalog, catalogue)" appears in that section. Also search in COLLECTIBLES > TRANSPORTATION > BICYCLES for the same.
