There are quite a few pics in the book 'DUCATI the untold story' bt Sir Alan Crashcart. Pics are a bit too big for my scanner and the Stella is kicking in,..............
Here's the cover pic ... "The front jacket photograph by phil masters shows marco lucchinelli winning aboard the eight-valve 850 desmo at the 1987 bott in daytona"
There's also a big double page shot and a couple of half-page-ish grid pics.
And in the virgin 'ducati - the official racing history' there are a couple of pokey pics.
