The original Boston bag was a very popular bag among the Boston students back then. Oblong and wide at the bottom and tapered at both ends towards the top opening, it was easy to understand why it was so popular! The shape could fit in all kinds of books and was practical for school. Dolly Club has since made a mini version of this Boston Bag.. although the mini Boston bag may not be able to fit in books, it is a great companion for those days when you are out and about.
