What is the difference in a 2 eye and 6 eye record


Was there any difference in quality of the pressings?

History of the Columbia label can be found here:

The new Jacob Dylan album called "Seeing Things" has been issued by Columbia with a 6 eye label! Got a pretty good sound too, not to compare it to a 50's 6 eye. It is nice to look at though!
