A couple of them are available in the Gallery section of this site. 4th from the top, second from the bottom, and the one of Lum holding Ten and sleeping, are guaranteed to be there.
Good Luck finding these (I'm hoping for some links, too, so I can add to MY collection)
avariciously yours, Veehive

Damn. That's all? Oh well, would you mind providing direct links to them?
