Doing presentations in graduate school in the early nineties (aka the dark ages) meant black and white over heads, not powerpoint (or keynote for you mac users) presentations, with photos and color graphs and builds and animations and imbedded video files. It was primative. Toward the end of my schooling, powerpoint became more common. Hell, I can remember glass slides (although I have sleeves of ppt slides that I will never ever use again but can not bear to throw out).
The point? Since I there was no such thing as clip art and I could draw, my friends were always asking me to draw little pictures that they could include on their overheads. Recently I found a book of such drawings.
The "take home" message was a favorite expression of a professor of mine (who loved to verbally spar with me, in a collegial way) and the caricature bears more than a passing resemblance to him. Score one for me (and my sartorial splendor!!).
And the reason the guy doing push ups has a ball and chain on his leg is because my buddy was giving a lecture on proper exercise at a correctional institution. He said they loved it.
