Do you teach these courses?  Here are some cartoon "study sheets" that can be copied and handed out to all.  A bit of humor is welcome - especially just before finals!  My students found these helpfull in sumarizing the essential  concepts of the course taught.  They will ask a lot of questions after seeing the text's concepts rendered in this light-hearted format.

Each cartoon fits on a 11 x 17 inch sheet that will be copy-friendly.  Price: $ 10.00 ppd each for the master.
