Friends, it's really really strange, and most upsetting, but no matter
what I do with the Willis photo, I just can't make Mr. Lewis' shirt appear..........
white.

You know, like the way it is showing up in Bell,
with blue to its left and right:

If only this could be achieved, then all this mad conspiracy-kook talk about Mr. Lovelady's shirt being visible in Bell could be put to bed. I mean, we KNOW at a deep metaphysical level that this has to be Mr. Lewis in Bell, but Mr. Lewis------------heaven forgive him-------------has given grist to the kook mill by
putting on the wrong darn shirt.
Now I'd dearly like to help Mr. Organ out by using the
Soopah-Doopah-Sun-Analysis he has so ingeniously used in the past to magic Mr. Oswald's brown arrest shirt into the off-white shirt seen by SN witnesses, but Mr. Lewis in Willis is
already in the bright sun, so it's just a really tough assignment bleaching that pesky blue of his away. Like,
none of the filters or other magic tricks seem to be working...........
Why, it's enough to make a man tear out his hair!!!

The very best I've been able to come up with is this button:

What with the nuclear blast from the sun, and the specific camera system and processing method with the Bell film, this button's unmistakeable whiteness could be blazing forth in Bell, giving kooks who don't understand camera systems and processing methods the erroneous impression that this is in fact Mr. Lovelady's white tshirt........

Yes. That must be it.
