Here's one of those timeless old college traditions: sanctioned graffiti.
I'm 99 percent certain that this is on one of the front display windows at J&M's South College Street bookstore. That very talented guy is touching up an artistic ode to head football coach Ralph "Shug" Jordan.
Apparently they were going to paint all of the windows up for whichever game or event this mural was commemorating.
Someone might come along and correct me here, but the artist does look a bit like Trey Johnston, who now runs the J&M stores. Maybe a little too tall, but there is a resemblance, going on the profile alone.
Nice to see he had the frat daddy look going, regardless of who it is. And the girl down the wall ... well, I'll save the bell bottom comments for a bit. The girl kneeling to work on her paint? She just came right across the street from Biggin Hall and the art department. Possibly nothing about these students have changed.
Give the 1970s artists this: they did some good work. During my time most of the drawing on the windows was text based, and devoid of a lot of this detail.
