Sports team schedules are usually free and can be picked up almost anywhere. I know I usually get a few from grocery stores and I have even seen them at restaurants. I usually pick one up (if I don't already have it) whenever I see one no matter the sport or team.
The schedule below was probably given out free at the Insurance company. Its from 1939 and has both Mizzou and Wash U (in St. Louis) schedules on it. I got it off ebay a long time ago for a buck or two. It's probably one of the first MU collectables I ever bought. (It has nothing on the back so I didn't scan it). I doubt its worth anything but it looks pretty cool.
