Great picture, for my money that's the best derivation of the Europa theme as far as design goes. The nice clean front of the S1, no chrome door handles sticking out and yet civilization with electric windows !
For some reason I'd thought that by 69 we were all on S2's although I suppose they could just have grabbed a '68 car for the shot, the design still looked pretty amazing.
As an aside, I quite like going back through old magazines and seeing the reaction to the cars back in the day. I just picked up a copy of Motor Sport where the "all new, radical Lotus" has been announced although not tested. It sounded like they went along but the car wasn't working.... now there's a Lotus for you
