Lost vintage leather-bound travel guidebook titled 'New Orleans: The Ultimate Guide' near Jackson Square in the French Quarter.

I lost my beloved vintage travel guidebook titled 'New Orleans: The Ultimate Guide' while strolling through the French Quarter last weekend. It's an older leather-bound book with maps and local tips handwritten throughout. I last remember having it near Jackson Square. It holds a lot of sentimental value as it was gifted to me by my grandmother, who used it during her visits. If anyone finds it, I'd be super grateful!
