The Helmet Project site details the various football helmets of all sorts of college and professional football teams, including (as the image to the right would suggest) the USFL! It also has some leagues that I had even forgotten existed, such as the international leagues (World Football League and World League of American Football turn NFL - Europe). It also had leagues that I wasn't aware of (two Arena Football leagues?) and some that I'm certain we'll all forget of and our kids will have never heard of (ahem, XFL).

What's particularly impressive is their college football team catalogue, including just about every conference (including I-AA ones such as Southland and some Division II and III as well). The scope of this web site, with not only their current helmets but their past ones too, is enormously impressive.

On another note, this column follows where all the NFL teams that have come and gone since the starting of the NFL.

And lastly, this site has a history of the ill-fated United States Football League, guest-starring Donald Trump as the villain!
