Dark brown leather Filson briefcase with green pen loop

I lost my dark brown leather Filson briefcase yesterday around 3pm near the Book Nook Café on Washington Ave in downtown Holland. It's a medium-sized bag, about 16 inches wide, with two sturdy handles and a zipper that sticks a bit in cold weather. The leather is gently worn with a small dent on the bottom-right corner, and there's a coffee ring on the back. Inside there's a black laptop sleeve and a green fabric pen loop that sticks out from the front pocket. It holds important work notes and a charger, and I'd really appreciate getting it back.
