Dave and Gene

Super-evocative photo. Photographer unknown.

Dave Aldana, Gene Romero and an unknown (to us) Yamaha XS jockey, lining up for the Peoria TT.
Romero running drum front brake while the privateer has a single disc and Aldana has twin.
Romero keeping faith with a Jet helmet rather than a full-face Star.
Aldana on a Trackmaster Norton (I'm pretty sure).

Thanks to Roger F for forwarding it. G
