Found brown leather satchel containing a notebook, pens, and a student ID card on the steps of the Michigan Union.

I found a brown leather satchel on the steps of the Michigan Union last Saturday. It looked like it had some important items inside, including a notebook, a few pens, and what seems to be a student ID card. I couldn't find anyone around to return it to, so I'm hoping to track down its owner. If you think this could be yours, please give me a description of the bag or its contents!
