I'd love to see marketing material from this era (to see where the bike fit into Dahon's lineup, how the company marketed its mountain bikes), any kind of specific photographs of this bike (the seat on mine isn't original, etc), as well as folding instructions (sequence of tightening the investment cast allen fittings).

Like that. Brochures and Owner's Manuals increase an older bike's value -- in this case, I'm thinking this is one of the earliest 26" Dahons!
