I spent many years traveling the US on a computerized recumbent bicycle (the Winnebiko and BEHEMOTH, from 1983-1991), and my library still carries many echoes of this magical time. These were in a file folder, long-forgotten bits of history that should find their way to a recumbent rider or historian. Lots of articles (that 1994 one is a 60-page double issue) and a real snapshot of the 'bent scene in the early nineties. Also included is a small catalog from Millennium, and (not shown) a photocopy of a Vic Sussman article called "Recumbent at the Wheel." 

And, of course, I'll include something of my own at no charge... whatever fits within the 1-pound first class shipping limit.
