This may sound silly, but take a look at the ATA logo. You would think the two "A's" on either side of the "T" would be the same/mirror images of each other. But one "A" is different from the other. They look close enough that you wonder if it was done intentionally or by accident.
It's a small detail, I know. But it makes the logo look somewhat amateurish.
If anyone knows the history behind the logo I'd like to know.
