I don't know if this has been brought up on here before, but there is a website selling these cool books called the College Vault series: College Vault Books: Big 12 Football and basketball: College Vault Books: BIG 12 Football
They have old photos plus old tickets, pennants, brochures, and whatnot that can be taken out of the book. If you want to see what some of them look like, the dude who does the UniWatch blog on ESPN did a little profile on his website: Uni Watch » Uni Watch Book Club: The College Vault Series
Anyway, they don't have ones for ISU yet, but you can go to the site & request one. If they get enough requests, they'll put one together. So click on the link and request ones for ISU football & basketball so I can get my wife to buy me one for my birthday.
Re: College Vault
That would make my Christmas. Very cool, and thanks for the heads up.
