Thanks to Kurt Busiek's Twitter feed, I found this letter's blog that goes in detail about a lot of comics Logos and how they were designed. I know it is kinda weird to spend hours reading about that stuff, but I just spent a good 20 minutes reading all about Daredevil's logo designs over the years.
I am onto the Justice League next, but if you guys want to check it out
HERE is the link. Just scroll down a tad to see his links to all sorts of titles.
Pretty cool stuff from a cool side of comics that gets little to no credit from fans.
