Sorry to crash....
Yep, I pledged in the early 80's and we had "bitch bags". They were just your average canvas tote bag (about 14" x 18") with the sorority name all over it in a sorority color.
like this:
kappa delta kappa delta kappa
delta kappa delta kappa delta
kappa delta kappa delta kappa delta
kappa delta kappa delta kappa delta
kappa delta kappa delta
I wish I still had mine. It was cute!
ETA: I looked for an old photo of someone with one but didn't find any. You might have some luck with photos by asking in one of the general forums. (what would it be? Chit chat? Greek life?)
