I found a graphic I wanted to use for the Old Playbook posting: a football playbook from Amos Alonzo Stagg's days as coach at University of Chicago. How he beat Ohio in 1922, for example. That's an old playbook!
I felt drawn to this graphic because I went to University of Chicago, as did my mother and father and aunt and husband and daughter. Also, the first nuclear reaction (The Italian Navigator) took place under the stands at Stagg Field at University of Chicago.
Alas, my request for permission to use the graphic is still bouncing its way up the chain of command at the University. So all I can provide is a link.
