Thanks for the comments on the USFL fields. I am having a bit of trouble with the Pittsburgh Maulers Logo and the Memphis Showboats Word mark. Hopefully I can get those worked on this weekend. Then I can work on the Orlando Renegades, and Arizona Outlaws.
College logos are by far and away the hardest to get a hold of in my experience. Why these univ and colleges do such a poor job in preserving their history Ill never know. If found a couple of great books on college mascot name origins from the 80s. They are both chock full of great vintage NCAA logos. I've been toying with the idea of doing a book review on some of the books in my collection.
