Dooney & Bourke Black Shoulder Bag

I have absolutely no idea if this is an authentic Dooney & Bourke bag as I cannot seem to find anything else like it and it uses a creed similar to Coach instead of the usual red, white and blue tag. It was believed to be authentic when purchased, but I cannot confirm that for sure. That being said, it seems to be a very well built bag. It has a unique mechanism for the strap that allows it to be a handbag or extended into a shoulder bag. The fabric had some slight pilling, which can be seen in the photos.
