Great article! You forgot to mention all the other cool paper like training binders, press and media kits and internal paperwork! None the less I've enjoyed collecting paperwork over the past 4 odd years or so, and there's always tons of stuff to look for because frankly, we don't even know what all is out there as far as promotional paperwork that was never advertised or available to the public.
