I think it's a MINI advert....Automobile Mag May 04
In the May 04 issue of Automobile Magazine, there's an insert called "Men of Metal", billed as an excerpt from the book by Rowland Samuel.
It's pretty hilarious, basically it's a story set in Oxford that involves UFO sightings and such. With no apparent MINI markings, MINIs are featured throughout, especially an object removed from a train track, identified as a MINI tailpipe, based on its classic beer can shape (the picture's funny).
Check it out.....apologies if this has already been spotted....
