This little Gucci bag looks like any other Boston/Doctors bag, until you look a bit closer. This bag does not have the serial # on the reverse of the inside logo tag, instead it's on the front logo plaque. At first I thought this was not a genuine bag, however after doing a bunch of research, it turns out that this bag is likely a prototype, or a model/sample/test version/concept bag, or perhaps even a runway bag. Since it was not produced for sale to the public, there is no serial #, but there is a Gucci patent number instead. I have found one other Gucci piece with the same logo plaque, it's a small coin purse that also never made it to production, as there is no other (exactly) like it. The bag is in overall great shape, there is some discoloration/staining to the bottom, and the latch that holds the zipper pull is not fully operational (seems to need to be tightened or adjusted(?). Comes with a Gucci dust bag.
