I did see this, clearly not an official one http://www.ebay.co.uk/itm/LIGHT-BOX...115533?hash=item1c932a6d4d:g:QsYAAOSwA3dYhRFB
This was up for £35.00 the other day - official Ducati Team Xerox travel mug circa 2005/06 WSB. Offered the chap £15 inc post and he accepted (another trinket for the cabinet)
Here's a rather tasteless one £695 !!!!!!!!!!!! http://www.ebay.co.uk/itm/BESPOKE-D...037939?hash=item46623037f3:g:cSEAAOSwtZJY~yaS
And this one is cool http://www.ebay.co.uk/itm/Ducati-Si...390969?hash=item3621ce20f9:g:DOgAAOSw-0xYkgzw
I'd be too tempted to re-arrange it to write the rudest word I could with it. (Not that I can think of any good anagrams for Ducati of the top of my head).
I've got a nice laser etched wood & wood framed image of my bike & online tag. Ian who's the service manager at OYB /Aylesbury ducati - son in law does them. I can't recall what I paid but I have on some thread pasted the details.
