Purchased in 1989 or maybe 1990. Approximately 15 1/2" x 15 1/2".
I haven't taken very good care of it... No one thought about collecting back then. Everyone just wanted the newest and latest and we all kept buying, not saving...
I used this bag a lot and thought I would throw it out when it got too worn. (Hangs head in shame.) Now I wear it to shlep around.
Please note the close-up of the leather... it's lambskin and I have never protected/condtioned it... it's not in terrible condition. I think Chanel leather holds up very well, over the years.
