Hi all ! I discovered this bag at a resale shop, at first I thought it was just a nice bag from Neimans as it had the store label, I peeled it back to reveal a Bonnie Cashin for Coach label. I've held on to it for a while, though I've never really determined what it would be used for. My first guess is an overnight bag ? It's sides are hard sided like a travel bag, enormous kiss lock pocket on one side, and odd zip on the other. Also, am I'm right in guessing its 1960s ? Looks like it fit a modern lap top ! Many thanks in advance !
