"Born to Trouble: Huckleberry Finn"

I want to buy a copy of the VHS or the DVD, which appeared on PBS in about 1969. I've used it for years in my American Lit. class before we read the novel "Huckleberry Finn." It's a great introduction to the controversy about requiring the novel. I lent it to a student who missed class the day we showed it, and I never got it back. So take pity on an old English teacher and sell me your copy!
