Let me ask:

What about the famous shirtless photo of Mark Twain, which is
usually published with some kind of comment about it not being
known how it came to be taken.

Is there an element of eroticism, maybe even [____]eroticism,
in that photo?  I know of no similar shots of 19th century
authors or celebrities.  So this is unusual, and it's unusual
in a particular way.

Now, you guys who want to deny that there's any "evidence" of
any of this sort of thing, well, I invite you to prove the
non-eroticism of such a photo by supplying the Twain Web with
a bare-chested photograph of yourself.  How about it, Mr. Caswell?
Mr. Britton?
