Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

This is a collage showing Jack Ruby's hair, and I suspect that, even as bald as he looks, some enhancement was done, that some of those strands on top are fake. For instance, compare the top right to the bottom right, and notice the additional strands on the bottom right. How easy would it have been for an artist to do that? 

Notice how far down the fringe of permanent hair is on Ruby. That's low even for a bald guy. The only way a guy with that low a fringe could have strands of hair top-center is by way of a hair transplant, which didn't exist at the time. So, even these images of sparse hair were enhanced. But, compare to the press photos, such as this one.

But, why did they do it? They did it because the Garage Shooter seemed to have such a mop. And it was a mop; it was a wig. James Bookhout had a standard FBI haircut, which was very short and very razored. For the Garage Spectacle, he wore a toupee'. This certainly isn't Jack Ruby's hair.
