Phantom Regiment's 1996 "Black Light" flags: in-person, they looked like a white flag with a black box in the middle, but were actually purple and white. Also, the white 2005 ballad flags fit the music's mood to a "T".
Cavaliers 1998 opener flags, the ones with the purple and white diagonal zebra-stripes.
Cadets 1995 opener flags, kind-of reminds me of a patchwork quilt (and probably felt like one, spinning them on seven-foot poles).
Blue Knights 1994 opener blueish flags on the wooden poles, and the tri-color red-white-green flags (they remind me of Madison's old flags from the early 1980's).
I honestly don't know where to find other pictures of these flags.
