Navy North Face backpack with initials P.P.

I lost my navy blue North Face Borealis backpack yesterday around 3pm outside the Yale Bookstore on College Street near Elm Street in New Haven. It's a medium-sized bag with a padded laptop sleeve, a bit of wear on the bottom corners, and a bright orange rain cover tucked into the side pocket. My initials 'P.P.' are embroidered on the front, and there's a small photo collage of my family inside the main compartment. It has sentimental value and I really need it back—it's my daily bag that carries my laptop, notes, and charger.
