I got this mail from Nona from The Compleat Sean Bean:
The British film magazine Empire has a LOTR preview story in its April 2001 issue which has a huge picture of Sean Bean as Boromir which we've previously only seen as a very small thumbnail.
I have it in my press archives on this page:
if you want to snag a scan of it.
If you want a nice big scan of the picture of Sean by itself, I have it here, if you want to download for your own use.
