Here is an emblem collection Tarjak put together several years ago, containing every emblem he could find at that time. Many of them are very unhistorical, including logos from modern American football teams. If you don't like certain ones they're easy enough to remove or just not use. They include the emblem packs created by CapZap, Church, and EvilJester.
