Navy blue canvas tote bag with leather handles

I lost my navy blue canvas tote bag with leather handles yesterday around 3pm outside the Barnes & Noble at Christiana Mall in Newark. It's about the size of a large tote, with a small brass zipper pull and a tiny coffee stain on the inner pocket. Inside I had a spiral notebook with a turquoise cover, a brown scarf tucked in the side pocket, and my keyring with a pink silicone fob. The bag is sentimental to me—it's a gift from my aunt and holds sketches and notes I was working on. If anyone found it, I’d really appreciate getting it back; I’m really worried about the notebook contents and what it means if it stays missing.
