Yea, I thought about that, the WTC picture the lenses are thicker, but that could be that the WTC eyeglasses are "glass" or "polycarb" and the current picture could be newer glasses made with thinner materials (I know because my son wears 'coke bottle' lenses and now has thinner ones, and a set of glasses only lasts a couple of years usually.
Also, that WTC "photo" could be several years old. The nose and mouth seem to be the same shape, but with that wool cap it's hard to guess what the WTC hairline is/was....hmmm
Also both have similar chins. But the distance from the tip of the nose to the top lip looks all wrong.
That is a tough call. I don't think it's him, though.
