This picture represents each of the HP professors we've met in the books, and their Butler Music Center counterpart. I had the help of my friend Tat to come up with which professor represented which professor, hehe. Since then most of the music faculty at Mansfield University has changed (in potter terms, Lupin left to get his doctorate, Binns retired, Trelawny has moved on and was replaced by 2 people, Flitwick retired and got married, and I really don't know who else is the same...)
