Klondike: Carrels in the first suggest library streak - UC Berkeley perhaps? If so, it doesn't look like vidcap (as the one above and the rest in my folder are); perhaps another year? Either way, quality is way better, and maybe more are out there... Second: Based on "Freak Streak" on the one back, I'd guess Southern Illinois University Edwardsville, Thursday or Friday, early March, 1974; see

P.S.: Clicking the link it said I needed to register, but Googling "Freak Streak" and clicking from there (it was on the 5th page of my search) worked fine.
