There was a very nice Brooks B18 (classic embossed women's saddle) poster of a naked chickie with a "peace" tattoo straddling her bike outside #10 Downing Street holding a placard of some sort.

Not dirty at all (the pic was from the back) and quite, umm, true to life. I could ride my B67 nekkid without my girlie-bits suffering. (B18 has the same dimensions with a shorter nose)

anybody got the link?
