Yeah, that thought crossed my mind, too. They both had model ships at some point, didn't they? Hutch had one in some very early eps, I think.

Thanks - actually, these didn't even take that much time! Even the United Nations one, though the title was quite unreadable, was quickly identified with an image search with terms "books about united nations" and image color restricted to black. Voilà.

Sometimes this is almost too easy, and other times no amount of squinting and Google tricks gets one anywhere. Uh-huh, I've spent insane amount of time trying to track down some LPs from Hutch's small collection, but damn, there's too little go on.
