chalkboard drawing

I was recently commissioned to do a chalkboard drawing for Reed College Reunions. If you're back at Reed, you can see this in Kaul Auditorium. For everybody else, here's what it looks like:It was a real treat to work on such a large scale. (Note: to cartoonists, anything bigger than a 3" by 3" square is considered large scale.) So as not to become overwhelmed, I made a small collage and printed it on a transparency. I then borrowed an overhead projector (which was covered in dust; no one uses these brilliant contraptions anymore apparently) to project the collage onto the chalkboard. The chalk drawing was done with sidewalk chalk and wet-erase chalk markers for the lettering.
