Blue leather address book with handwritten contacts

I lost my blue leather address book yesterday around 3pm near the North Market on Market Street in Columbus. It's pocket-sized, about the size of a passport, with a worn spine and a coffee stain on the back cover. Inside there are several pages of handwritten numbers and notes, including my emergency contacts section marked with a tiny red star sticker. A blue ribbon bookmark pokes out when you flip to the contacts. This book has sentimental value—it's where I keep my family and coworkers' numbers—and I really need it back.
